Peter is overweight. he is 105 kg. his aim is to lose 500 g per week. if he manages this, how many weeks will it be until he is 90 kg?

30 Weeks

Step-by-step explanation:

Subtract 90 kg from 105 kg. (15 kg left over)

Since we are now measuring in kilograms, we have to turn the 500 g into kilograms.

1000 grams make up a kilogram, but we have 500 grams. Convert 500 grams into a kilogram. (0.5 kg or 2 kg)

Multiply: 15 x 0.5/2= 30

It will take Peter 30 weeks for him to weigh 90 kg.
