Lena would be able to finish 10 math homwork problems. 15*5 equals 75. So multiply 2 by 5 and thats how many problems Lena can do in 75 minutes.

Set up a proportion.
(x is the amount of problems she can do in 75 mins)

\(\frac{2}{15} = \frac{x}{75}\)

Now, to find 'x', we need to have it on its own, so we multiply by 75 on both sides.

\(\frac{2}{15}\) × \(75 = x\)

The answer is 10, as \(\frac{2}{15}\) multiplied by 75 is 10.
