Cut one amount into equal shares. One number tells you what a share is worth.
In this one. The gap between the two ratio bars is a gap you already know: Males − Females = (Boys − Girls) + (Men − Women) = 69 + 54 — compare the differences you were given, not the totals you don't have.
A single amount is split by a ratio, a fraction or a percentage. One extra number gives you the leftover, the difference, or the value of one share.
Children match the given number to the wrong number of shares, using the whole bar when the number covers only the leftover or the difference between two people's shares.
