The explanation is much longer than doing the mathematics.   The ratio of 15 boys to 10 girls is equivalent to the ratio of 3:2  Explanation:   Consider the starting point:   We have 3 boys and 2 girls. This gives a total count of 5   So we need to see how many lots of 5 will fit into 25.   5 lots of 5 gives 25   So we have 5 lots of the ratio 3:2  5 lots 3:2→5×(3:2)=(5×3):(5×2)=15:10

Write the ratio in fractional form We can do this as long as we do not view and treat it like a fraction It does not matter in this case which we put on the top. I chose: boysgirls→32 Multiply a value (or system) by 1 and you do not change the value. However, 1 comes in many forms. 32×1→32×55 =3×52×5 =1510=boysgirls The ratio of 15 boys to 10 girls is equivalent to the ratio of 3:2 15:10≡(15÷5):(10÷5)=3:2 where ≡ means equivalent to
