Question

Andrea had 32 problems to do for mathematics homework over the weekend. She did 1/4 of the problems on Friday night, and on Saturday she did 1/4 of the problems that were left to do. What was the total numbers of problems that Andrea needed to do on Sunday in order to complete her mathematics homework?

Answer 1

Andrea needs to solve 18 mathematics problems to complete her homework.

Step-by-step explanation:

Given,

Total mathematics problems = 32

Problems solved on Friday night = $\frac{1}{4}\ of\ 32 = \frac{1}{4}*32$

Problems solved on Firday night= $\frac{32}{4} = 8$

Problems left = Total problems left - Problems solved on Firday night

$Problems\ left=32-8\\Problems\ left=24$

Problems solved on Saturday = 1/4 of problems left

Problems solved on Saturday = $\frac{1}{4} *24 = \frac{24}{4}$

Problems solved on Saturday = 6

Problems left to solve = Problems left on Friday night - Problems solved on Saturday

$Problems\ left\ to\ solve=24-6\\Problems\ left\ to\ solve=18$

Andrea needs to solve 18 mathematics problems to complete her homework.
