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?

30weeks

Step-by-step explanation:

105kg-90kg=15kg

1kg=1000g

x=500g

500g×1kg=1000g×

x=0.5kg

if 1week=0.5kg how about 15kg =to how many weeks

15kg×1week÷0.5kg=30weeks

so, the and is he requires 30 weeks to have 90kg

It will take him 30 weeks.

Step-by-step explanation:

500 g is equal to 0.5 kg.

He wants to lose 0.5 kg a week.

For this to happen we must subtract 105 - 90 = 15.

2 x 1/2 = 15 x 2= 30.

It will take him 30 weeks to lose weight.

You welcome hoped this helped! :)
