Answer 1

The number of problems are correct in the math quiz be 35 .

Explanation:

Let us assume that the number of problems are correct in the math quiz be x.

The math quiz has 45 problems.

`Martha\ got\ (7)/(9)\ of\ them\ correct.`

Solving the above

`x = (315)/(9)`

x = 35

Therefore the number of problems are correct in the math quiz be 35 .
