Elementary School Math Quiz: Add And Subtract Unlike Fractions

A recipe uses the same-sized whole cup as the unit. Maya pours $\tfrac{2}{3}$ cup of milk and then adds $\tfrac{1}{4}$ cup more. What is the total amount of milk she poured?

A ribbon is cut from the same-sized roll. Maya uses $\frac{3}{4}$ meter, and Jordan uses $\frac{2}{3}$ meter. What is the total length of ribbon they use?

A recipe serves 6 people and calls for $1\frac{1}{3}$ cups of milk and $\frac{3}{4}$ cup of cream. Maria wants to make enough for 9 people. How much total liquid (milk and cream combined) will she need?

A recipe calls for $2\frac{1}{6}$ cups of flour. James accidentally added $2\frac{3}{4}$ cups instead. If he removes $\frac{1}{3}$ cup to try to fix his mistake, how much flour will he have compared to the original recipe?

On a hike, Noah walked $\frac{3}{5}$ mile and then $\frac{1}{2}$ mile. Both distances are parts of the same 1-mile whole. He rewrote them as $\frac{3}{5}=\frac{6}{10}$ and $\frac{1}{2}=\frac{5}{10}$. Which statement about the size of the result is correct?

A garden bed is the same whole garden bed for both measurements. One section is $\frac{7}{8}$ full of soil, and another section adds $\frac{2}{5}$ of the bed more. The fractions must refer to the same whole (one garden bed). A student rewrites them as $\frac{7}{8}=\frac{35}{40}$ and $\frac{2}{5}=\frac{16}{40}$. What is the total fraction of the garden bed filled?

A recipe uses flour measured with the same 1-cup measuring cup. You already added $1\frac{1}{4}$ cups of flour, but the recipe needs $2\frac{1}{3}$ cups total. The fractions must refer to the same whole (1 cup). Using equivalent fractions, $\frac{1}{4}=\frac{3}{12}$ and $\frac{1}{3}=\frac{4}{12}$. How much more flour is needed?

Two pitchers each hold the same 1-liter whole (fractions must refer to the same-sized whole). One pitcher has $\frac{7}{8}$ liter of juice. Another has $\frac{1}{3}$ liter of juice. A student writes equivalent fractions: $\frac{7}{8}=\frac{21}{24}$ and $\frac{1}{3}=\frac{8}{24}$. What is the difference $\frac{7}{8}-\frac{1}{3}$ liters?

A science class pours water into a container, using the same 1-liter measuring cup each time. They pour $\frac{5}{6}$ liter, then pour $\frac{1}{4}$ liter more. The fractions must refer to the same whole (1 liter). One student rewrites them as equivalent fractions: $\frac{5}{6}=\frac{10}{12}$ and $\frac{1}{4}=\frac{3}{12}$. What is the total amount of water poured?

Liam filled a water bottle that holds 1 whole liter. He drank $\frac{7}{8}$ liter and then drank $\frac{1}{3}$ liter more from another identical full bottle. The fractions refer to the same-sized whole liter. He rewrote $\frac{7}{8}=\frac{21}{24}$ and $\frac{1}{3}=\frac{8}{24}$. What is the total amount he drank?

On a number line from 0 to 1 (the same whole), a student wants to add $\frac{3}{8}$ and $\frac{1}{2}$. The student writes equivalent fractions: $\frac{1}{2}=\frac{4}{8}$. Which statement correctly explains how the fractions were combined?

A runner jogged $\frac{5}{6}$ mile on Monday and $\frac{1}{4}$ mile on Tuesday. Both distances are parts of the same 1-mile whole. Which statement correctly explains how to find a common denominator using equivalent fractions before adding?

A water bottle holds 1 whole liter (the same-sized whole). A student drank $1\frac{1}{2}$ liters over the day from refills, then drank $\frac{2}{3}$ liter more. These amounts refer to the same unit (liters). The student rewrites $\frac{1}{2}=\frac{3}{6}$ and $\frac{2}{3}=\frac{4}{6}$. What is $1\frac{1}{2}+\frac{2}{3}$ liters?

Two students ate parts of the same-sized pizza. One ate $1\frac{1}{2}$ pizzas and the other ate $\frac{3}{4}$ of a pizza. The fractions must refer to the same whole (one pizza). Using equivalent fractions, $\frac{1}{2}=\frac{2}{4}$. What is the total amount of pizza eaten?

Two students are measuring the same 1-yard strip of fabric (fractions must refer to the same-sized whole). One student used $\frac{5}{6}$ yard. The other student used $\frac{1}{4}$ yard. They find equivalent fractions: $\frac{5}{6}=\frac{10}{12}$ and $\frac{1}{4}=\frac{3}{12}$. What is the difference $\frac{5}{6}-\frac{1}{4}$?

A recipe uses the same 1-cup measuring cup as the whole. You have $2\frac{1}{4}$ cups of flour and you add $\frac{2}{3}$ cup more. You rewrite $\frac{1}{4}=\frac{3}{12}$ and $\frac{2}{3}=\frac{8}{12}$. What is $2\frac{1}{4}+\frac{2}{3}$ cups?

A science class uses the same 1-meter strip as the whole length. One group measures $\tfrac{5}{8}$ meter. Another group measures $\tfrac{1}{4}$ meter. They add the lengths and use equivalent fractions: $\tfrac{1}{4}=\tfrac{2}{8}$. Which statement about the size of the result is correct?

Two students are measuring water from the same-sized 1-liter bottle, so the fractions refer to the same whole. They need to subtract: $\tfrac{5}{6}$ liter minus $\tfrac{1}{4}$ liter. Which statement correctly explains how to find a common denominator using equivalent fractions?

A baker uses the same whole tray of brownies. She has $2\tfrac{1}{3}$ trays made and gives away $\tfrac{3}{4}$ tray. She rewrites $\tfrac{1}{3}$ as $\tfrac{4}{12}$ and $\tfrac{3}{4}$ as $\tfrac{9}{12}$ so the fractions refer to the same-sized whole tray. How many trays does she have left?

A class has 1 whole hour for a science lab. They spent $\frac{2}{5}$ hour setting up and $\frac{1}{2}$ hour doing the experiment. Both fractions refer to the same 1-hour whole. The teacher rewrote them as equivalent fractions: $\frac{2}{5}=\frac{4}{10}$ and $\frac{1}{2}=\frac{5}{10}$. How much time did they spend in all?
