Cut one amount into equal shares. One number tells you what a share is worth.
In this one. Because the known $24 covers exactly 3 of the 10 equal budget units, dividing by 3 fixes each unit at $8 and turns the rest of the model into dollar amounts.
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.
