Answer 1

Answer:

Option A ( 10 )

Step-by-step explanation:

Given that Ruby has 30 problems for homework

Also, given that $\frac{2}{3}^{rd}$ of problems were worked out

So, number of problems solved = $\frac{2}{3}$ x 30 = 2 x 10 = 20

∴ Number of problems yet to be worked out = 30 - 20 = 10

Answer 2

Step-by-step explanation:

Total no. of problems = 30

worked out problems = 2/3 of 30

= 2/3 X 30

= 2 X 10

= 20

Now,

Left problems

= Total - worked out

= 30 - 20

= 10

So Ruby has still 10 problems left to work out.
