Exercise 84 Page 12

To compare different measurements, it's necessary for them to have the same unit. For this exercise, we can either convert 32 mm to cm or 3.2 cm to mm.

Converting cm to mm

We know that 1 cm equals 10 mm which can be written as the following conversion factor. 10mm/1 cm If we multiply 3.2 cm by this ratio, we can convert the measurement to mm.

Comparing the Measurements

Since 3.2 cm equals 32 mmm, we will use the equality sign. 32mm =3.2 cm
