These are all increases.

18 - 15 = 3

3/15 = 0.2 = 20%

Try the others, and I'll check your answers.

Thank you! Are these right?

$38 to $65

65-38=27

27/38=0.710 = 70%

125lb to 143lb

143-125=18

18/125=0.144= 14%

You're close.

27/38 = 0.7105 = 71.1% rounded to the nearest tenth

18/125 = 0.144 = 14.4%
