Numbers 2-3 =

2. For number 2, the only thing we need to do is multiply fractions. Before we multiply fractions, we have to turn a mixed fraction into improper by doing the denominator (3) multiplied by the whole number (2) then added to the numerator (1). After that, 2 1/3 should equal to 7/3 as our improper fraction. Now just multiply 7/3 by 2/5 to get your answer.

7/3 x 2/5 = 14/15 hours on Tuesday


3. This question is similar to the previous one. Convert mixed into improper then multiply.

3 1/2 = 7/2
1 1/3 = 4/3

7/2 x 4/3 = 28/6 = 4 2/3 feet tall



Numbers 1-3 =

1. Number one wants us to find out how many muffins she can make when each muffin takes 1/3 of muffin batter. The key word here is “each” indicating we have to divide. We have a total of 5 cups of batter, and each muffin needs 1/3 cups of batter. We just just gotta divide 5 by 1/3 to get the total amount. To divide fractions, we use a method called “KEEP CHANGE FLIP” basically changing the sign of the equation and flipping the fraction.

5 / 1/3 = 5 x 3 = 15 muffins
(KEEP CHANGE FLIP)


2. Same thing as the previous one. Use the method “KEEP CHANGE FLIP” to divide fractions. There are 5 people, and we need to split the 1/2 package equally.

1/2 / 5 = 1/2 x 1/5 = 1/10 of the package for each person
(KEEP CHANGE FLIP)


3. This is the same thing as the previous ones. We have to divide apples into quarters. Remember that quarters are 4 pieces. We have to divide 8 apples by 1/4.

8 / 1/4 = 8 x 4 = 32 apple slices
(KEEP CHANGE FLIP)

Hopefully this helped. If it didn’t, then please let me know!! Have a great rest of your day.
