Question

If 19 out of 110 chose volleyball. How many people would it be out of 330

Answer 1

19/110 = ?/330

330÷110= 3

so 3×110=330

19×3=57

whatever u do times the denominator by u have to do the same for the numerator.

therefore 57 people chose volleyball.

hope u understand my explanation.

110 330

using cross products
