shusha [124]

Answer:

Step-by-step explanation:

The answer is easy to find if we use the cross-multiplication method.

We know 7 students out of 10 picked apples, then 3 out of 10 picked bananas.

We know the number of people who picked apples.

$\frac{apples}{bananas} = \frac{7}{3} = \frac{84}{x}$

We just have to isolate x, this way and solve the problem:

$\frac{7}{3} = \frac{84}{x}$

becomes

$x = \frac{84 * 3}{7} = \frac{252}{7} = 36$

So, 36 students picked bananas as their favorite fruit.
