Question

The ratio of sugar to flour in a cake recipe is 3 to 5.

Marcus is going to follow the recipe to make a large
sheetcake. He starts by putting 12 cups of sugar in a mixing
bowl. How many cups of flour should he add?

Answer 1

He would need to add 20 cups of flour.

According to the problem Marcus puts in twelve cups of sugar, and the original amount of sugar was 3 cups. If you divide 12 by 3 you get 4. This means that you multiply 5 by 4 to get the total amount of flour required (originally there were 5 cups of flour).

Hope this helps and have a nice day.
