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

Answer:

Number of problems that is left for Andrea to on Sunday =18

Step-by-step explanation:

Total number of problems Andrea had = 32

Problems solved by Andrea on Friday night was $\frac{1}{4}$ of the problems which is =  $\frac{1}{4}\times 32=8$

Problems now left =$32-8=24$

Problems solved by Andrea on Saturday night was $\frac{1}{4}$ of the problems left which is =  $\frac{1}{4}\times 24=6$

∴ Number of problems that is left for Andrea to on Sunday= $24-6=18$
