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

• 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=(A)/(B)`
• So the rate is
  `((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
  `(3)/(2)=1.5\\so\\((3)/(2))cupsofflour/cupsofsugar = (1.5)cupsofflour/cupsofsugar`
