Express each ratio as a fraction in its simplest form: 8 dm to 3.2m

Answer 1

8dm/3.2m = 80m/3.2m = 80/3.2 = 10/.4 = 5/.2 = 50/2 = 25/1 = 25

1 dm = 10 m

You have to convert numerator or denominator so they both have the same units, then they cancel out and the ratio is unitless, "just" a pure number
