Question

in a baking recipe, there is a proportional relationship between the number of cups of flour and the number of cups of sugar. What does that mean? Tell at least two things you know are true about this relationship.

Answer 1

For every cup of flour, x amounts of sugar is also added. Vice versa. When creating a bigger batch, the numbers should always be proportionate with each other

Answer 2

By creating a proportion equation and applying the knowledge of fractions, the number of cups of sugar used for 1 cup of flour will be: cup of sugar.

To find the number of cups of sugar that will be used for a cup of flour, we would apply out knowledge of proportion and fractions.

Using proportion equation, we would create an equation to enable us look for the quantity of sugar that would be used for 1 cup of flour.

Using the table given,

cups of sugar was used for cups of flour

Therefore:

Let x represent the number of cup of sugars that will be used for 1 cup of flour.

Creating a proportion equation, we will have:

Cross multiply

Change the fractions to improper fractions and solve for x

Multiply both sides by 2

Divide both sides by 15

Therefore, by creating a proportion equation and applying the knowledge of fractions, the number of cups of sugar used for 1 cup of flour will be: cup of sugar.
