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: Which is greater on a number line: $0.62$ or $0.6$?

Answer: $0.62$. On a number line, $0.62$ is positioned to the right of $0.6$ because it includes an additional two hundredths.

Flashcard 2: What decimal represents the point halfway between $0.4$ and $0.5$ on a number line?

Answer: $0.45$. The midpoint between $0.4$ and $0.5$ is found by averaging them, resulting in the halfway point on the number line.

Flashcard 3: Choose the correct order from least to greatest: $0.4$, $0.04$, $0.404$.

Answer: $0.04<0.4<0.404$. Ordering decimals requires comparing place values, with $0.04$ smallest, followed by $0.4$, then $0.404$.

Flashcard 4: What decimal corresponds to $7$ tenths?

Answer: $0.7$. $7$ tenths equals $0.7$, representing $7/10$ in decimal form on the number line.

Flashcard 5: What decimal is one tenth greater than $0.37$?

Answer: $0.47$. Adding one tenth, or $0.1$, to $0.37$ shifts the point rightward by that amount on the number line.

Flashcard 6: Identify the missing decimal: $0.2$, $0.25$, $\square$, $0.35$ are equally spaced by $0.05$.

Answer: $0.30$. The sequence increases by $0.05$ each time, so after $0.25$, adding $0.05$ fills the missing term.

Flashcard 7: A runner finishes in $12.6$ s and another in $12.57$ s; who is faster (smaller time)?

Answer: The runner with $12.57$ s. $12.57$ s is less than $12.6$ s because $12.57$ equals $12.570$, which is smaller when compared in the same place values.

Flashcard 8: Which number is farthest to the right on a number line: $4.07$, $4.7$, or $4.17$?

Answer: $4.7$. Among the options, $4.7$ is the largest value, positioning it farthest to the right on the number line.

Flashcard 9: Which decimal is equivalent to $0.5$ written with two decimal places?

Answer: $0.50$. Writing $0.5$ with two decimal places adds a zero in the hundredths place, maintaining equivalent value.

Flashcard 10: What decimal represents $1$ and $9$ tenths on a number line?

Answer: $1.9$. $1$ and $9$ tenths combines the whole number with $0.9$ to position it correctly on the number line.

Flashcard 11: Which decimal is between $6.2$ and $6.3$ and equals $6$ and $25$ hundredths?

Answer: $6.25$. $6$ and $25$ hundredths combines to form a decimal between $6.2$ and $6.3$ by adding $0.25$ to $6$.

Flashcard 12: Which number is farthest to the left on a number line: $0.09$, $0.1$, or $0.099$?

Answer: $0.09$. Among the options, $0.09$ is the smallest value, positioning it farthest to the left on the number line.

Flashcard 13: What decimal corresponds to $35$ hundredths?

Answer: $0.35$. $35$ hundredths equals $0.35$, representing $35/100$ in simplified decimal form.

Flashcard 14: What decimal is $3$ tenths to the right of $1.6$ on a number line?

Answer: $1.9$. Adding $3$ tenths, or $0.3$, to $1.6$ shifts the position rightward by that distance on the number line.

Flashcard 15: What decimal is exactly midway between $3.1$ and $3.3$ on a number line?

Answer: $3.2$. The exact midpoint between $3.1$ and $3.3$ is calculated as their average, placing it centrally on the number line.

Flashcard 16: What decimal is one hundredth less than $0.50$?

Answer: $0.49$. Subtracting one hundredth, or $0.01$, from $0.50$ moves the point leftward by that increment on the number line.

Flashcard 17: Which is greater on a number line: $0.503$ or $0.53$?

Answer: $0.53$. $0.53$ is greater than $0.503$ because the tenths place dominates over the thousandths place on the number line.

Flashcard 18: A store price is $3.5; what is the same price written with two decimal places?

Answer: $3.50. Writing $3.5 with two decimal places adds a zero in the hundredths place, preserving the monetary value.

Flashcard 19: Which decimal is closest to $1$ on a number line: $0.98$ or $1.02$?

Answer: Both; each is $0.02$ from $1$. Both $0.98$ and $1.02$ are equally distant from $1$, each by $0.02$ units on the number line.

Flashcard 20: A bottle holds $0.75$ L; how many milliliters is this if $1$ L $=1000$ mL?

Answer: $750$ mL. Converting $0.75$ L to milliliters involves multiplying by $1000$, as $1$ L equals $1000$ mL.

Flashcard 21: Which decimal is closest to $0.3$: $0.29$, $0.31$, or $0.305$?

Answer: $0.305$. The distance from $0.3$ to $0.305$ is $0.005$, which is smaller than $0.01$ to the other options.

Flashcard 22: What decimal is $5$ hundredths to the left of $0.83$ on a number line?

Answer: $0.78$. Subtracting $5$ hundredths, or $0.05$, from $0.83$ moves the position leftward by that amount on the number line.
