How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: In a bar graph comparing salt water and fresh water, what does the height (or length) of a bar represent?

Answer: The amount (value) for that category. Bar size shows the quantity being measured.

Flashcard 2: Which unit is most appropriate for comparing parts of a whole like salt water vs fresh water: percent or meters?

Answer: Percent. Percentages show parts of the whole water supply.

Flashcard 3: Which ratio matches the data $97\%$ salt water and $3\%$ fresh water: $97:3$ or $3:97$?

Answer: $97:3$. Ratio format lists salt water first, then fresh water.

Flashcard 4: If a chart shows $100$ liters total, how many liters are salt water at $97\%$?

Answer: $97$ liters. $97\%$ of $100$ liters equals $97$ liters.

Flashcard 5: What is the difference in percentage points between $97\%$ salt water and $3\%$ fresh water?

Answer: $94$ percentage points. Subtract: $97\% - 3\% = 94\%$.

Flashcard 6: Which is greater: $\frac{97}{100}$ of Earth's water (salt) or $\frac{3}{100}$ (fresh)?

Answer: $\frac{97}{100}$ (salt water). $\frac{97}{100} > \frac{3}{100}$ since $97 > 3$.

Flashcard 7: What fraction of Earth's water is salt water if the data show $97\%$ salt water?

Answer: $\frac{97}{100}$. $97\%$ equals $97$ out of $100$ parts.

Flashcard 8: What fraction of Earth's water is fresh water if the data show $3\%$ fresh water?

Answer: $\frac{3}{100}$. $3\%$ equals $3$ out of $100$ parts.

Flashcard 9: Identify the correct comparison symbol for $97\%$ (salt) and $3\%$ (fresh).

Answer: $97\% > 3\%$. Greater than symbol shows $97$ is larger than $3$.

Flashcard 10: Identify the correct conclusion from data showing $97\%$ salt water and $3\%$ fresh water.

Answer: Earth has much more salt water than fresh water. $97\%$ is significantly greater than $3\%$.

Flashcard 11: What type of water has a high amount of dissolved salts: salt water or fresh water?

Answer: Salt water. Salt dissolves in ocean water, making it salty.

Flashcard 12: Which statement is correct if a table lists salt water $97\%$ and fresh water $3\%$?

Answer: Salt water is the majority of Earth's water. $97\%$ represents more than half, making it the majority.

Flashcard 13: Which is larger based on the data: $97\%$ salt water or $3\%$ fresh water?

Answer: $97\%$ salt water. Compare the percentages: $97\% > 3\%$.

Flashcard 14: What type of water has very little dissolved salt: salt water or fresh water?

Answer: Fresh water. Rivers and lakes contain minimal dissolved minerals.

Flashcard 15: If a chart shows $100$ liters total, how many liters are fresh water at $3\%$?

Answer: $3$ liters. $3\%$ of $100$ liters equals $3$ liters.

Flashcard 16: If Earth had $200$ liters total, how many liters would be fresh water at $3\%$?

Answer: $6$ liters. $3\%$ of $200$ liters: $0.03 \times 200 = 6$.

Flashcard 17: If Earth had $200$ liters total, how many liters would be salt water at $97\%$?

Answer: $194$ liters. $97\%$ of $200$ liters: $0.97 \times 200 = 194$.

Flashcard 18: Identify the correct reading: On a bar graph, the taller bar represents what when comparing water amounts?

Answer: A greater amount (or greater percent). Height corresponds to quantity in bar graph comparisons.

Flashcard 19: What is the name of a data display that compares amounts using rectangular bars?

Answer: Bar graph. Bars visually compare quantities between categories.

Flashcard 20: What is the correct meaning of salt water when comparing Earth’s water sources?

Answer: Water with dissolved salts; mostly found in oceans. Oceans contain minerals and salts dissolved from rocks and soil.

Flashcard 21: What is the correct meaning of fresh water when comparing Earth’s water sources?

Answer: Water with very little dissolved salt. Contains minimal salt content, typically less than 0.5 parts per thousand.

Flashcard 22: Choose the correct conclusion: A lake has $2$ g salt per L; ocean water has $35$ g per L.

Answer: Ocean water is saltier than the lake. Ocean has $35$ g/L compared to lake's $2$ g/L of salt.

Flashcard 23: What approximate percent of Earth’s water is salt water in most grade-level datasets?

Answer: About $97\%$. Oceans and seas make up the vast majority of Earth's water.

Flashcard 24: What approximate percent of Earth’s water is fresh water in most grade-level datasets?

Answer: About $3\%$. Only a tiny fraction exists as rivers, lakes, ice, and groundwater.

Flashcard 25: Find the salt water amount if a dataset shows total water is $1000$ L and salt water is $97\%$.

Answer: $970$ L. Multiply total volume by the percent: $1000 \times 0.97 = 970$.

Flashcard 26: Which option correctly compares $97\%$ and $3\%$ using a subtraction difference?

Answer: Difference is $94\%$. Subtract the smaller percent from the larger: $97\% - 3\% = 94\%$.

Flashcard 27: Identify the correct unit to compare amounts in a dataset labeled in percent (%).

Answer: Percent ($\%$). Match the unit shown in the data table or graph.

Flashcard 28: Which option best describes a pie chart showing $97\%$ salt water and $3\%$ fresh water?

Answer: Salt water slice is much larger than fresh water slice. The $97\%$ slice takes up nearly the entire circle.

Flashcard 29: Which is greater in typical Earth water data: salt water percent or fresh water percent?

Answer: Salt water percent is greater. Salt water at $97\%$ far exceeds fresh water at $3\%$.

Flashcard 30: Identify the correct comparison: if salt water is $97\%$, what percent is not salt water?

Answer: $3\%$. The remaining percent after salt water must be fresh water.
