Question

Someone needed to complete eight math problems and her dad said that she could take a break once she had finished 40% of it and she finished 3 problems so can she take a break

Answer 1

Answer: no

Step-by-step explanation:

use the proportion:

is/of = %/100

x/8 = 40/100

320 = 100x

divide by 100

x = 3.2 problems

she needs to do 3.2 problems. 3 is not enough.
