Question

ruby had 30 problems for homework she worked out 2by 3 of them, number. of problems still left to be worked out by her is​

Answer 1

Given:

Ruby had 30 problems for homework she worked out 2 by 3 of them

To find:

The number. of problems still left to be worked out by her



Solution:

​The total no. of problems Ruby had for her homework = 30

The no. of problems she worked out =  $\frac{2}{3} \times 30 = 2 \times 10 = \bold{20}$

Now,

The remaining no. of problems still left to be worked out is,

= [Total problems] - [Problems worked out]

= 30 - 20

= 10

Thus, the number of problems still left to be worked out by Ruby is​ → 10.
