Question

A recipe uses 3 cups of flour 2 cups of sugar write the ratio of flour to sugar. Then write the related rate and unit rate.

Answer 1

Answer:

• The ratio of a certain thing say A to another B is written as A:B

• To write this as a rate, put the left value A on top of the right value B so that $A:B=\frac{A}{B}$
• So the rate is $\frac{(3)cupsofflour}{(2)cupsofsugar}$  read as 3 cups of flour per 2 cups of sugar
• The unit rate means write the fraction as a rational non-fraction number so $\frac{3}{2}=1.5\\so\\(\frac{3}{2})cupsofflour/cupsofsugar = (1.5)cupsofflour/cupsofsugar$
