7 0

To solve, simply know that 1/5 of 20 is 4. How did you get that? You do 1/5x20. Which is 20/5. The answer is 4. Now multiply 4 by 4. 16. Now the left over 1/5 is 4. So, 4 is how many girls there are. (Make sure to label)

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
