There are many different ways to compare amounts or quantities. A ratio is a comparison of two quantities by division. For example, the ratio of a to b can be written in two different ways.
a/b or a: bWe want to find the ratio of red shirts to green shirts in a drawer. To do so, we will write the fraction that represents desired ratio. We will write the number of red shirts in the numerator and the number of green shirts in the denominator.
l red shirts→ green shirts→
4/8
Finally, since the greatest common factor (GCF) of 4 and 8 is 4, we can reduce the fraction by dividing both the numerator and denominator by 4.
