Hey there!
3/7 is needed for 1 cake
If she needs to make 42 cakes, then multiply the amount for 1 by 42
42 × 3/7 = 126/7 = 18
She needs 18 kilograms of flour to make 42 cakes
Hope this helps :)
Do you have a picture or anything that you could show us?
So as we already know the ratio is 3 quarts blue paint to 2 quarts red paint, also written as 3:2. if she only has 1 quart blue paint she will need half of a quart of red paint because the ratio has to remain the same amount. if you multiply one side then you must multiply the other. same goes with division. If she only has 1 quart of red paint then that shows she divided the 2 red by 2. There fore you would have to divided the 3 by 2 in order to get 1.5 which would then make the ratio 1.5:1
