Mike makes 4 dozen cookies. He brings 75% of them for a party at his school. How many did he bring?

baherus [9]

Answer:

He brought 3 dozen cookies

She ate $\frac{2}{5}$ of the bag of Doritos

She read 25 books

Step-by-step explanation:

∵ Mike makes 4 dozen cookies

∵ He brings 75% of them for a party at his school

- Multiply 75% by 4

∵ 75% = $\frac{75}{100}=\frac{3}{4}$

∴ He brought = $\frac{3}{4}$ × 4

∴ He brought = 3

He brought 3 dozen cookies

∵ Sam bought a bag of Doritos

∵ She ate only 40% of them

∵ 40% = $\frac{40}{100}=\frac{2}{5}$

∴ She ate = $\frac{2}{5}$ × 1

∴ She ate = $\frac{2}{5}$

She ate $\frac{2}{5}$ of the bag of Doritos

∵ Jamie took 50 books from the library

∵ She only read half of her whole stack

- Multiply half by 50

∴ She read = $\frac{1}{2}$ × 50

∴ She read = 25

She read 25 books

Matt is 24 and John is 18. 24 - 18 is 6. And 24 + 18 would equal 42.
