Question

A baker has 9kg of butter. he uses 3/7kg ot bake 5 loaves of bread. How many loaves can he bake with the butter?

Answer 1

9 divided by 3/7 = 21
so, he can make 21 * 5 loaves = 105 loaves

algebraically, you want to convert loaves to kg

you can always multiply by 1 without changing anything

5 loaves = 3/7 kg
so,
1 = 5loaves/(3/7)kg

so,

9kg * 5 loaves/(3/7)kg = 45/(3/7)loaves = 105 loaves

Answer 2
