Question

A squash ball weighs 23000 mg ,a golf ball weighs 45g, a basket ball weighs 0.65 kg and a football weighs kg.Arrange the names of the sports in order of weight of the ball from the heaviest to the lightest.

Answer 1

For the purpose of arranging these balls in order of weight, you put all the balls' weight in the same unit of measurement. In this case we will use grams

-squash ball 23000mg
1000mg = 1 g
therefore 23000mg =  23g

-golf ball = 45g

- basket ball 0.65kg
1kg = 1000g
therefore 0.65kg=  650g

Football-  (a football weighs between (0.41-0.45kg) ....lets use 0.45kg
1kg =            1000g
Therefore 0.45kg = 450g

Basket ball-650g, football-450g, golfball- 45g, squash ball- 23g

Therefore the order is as follows:

Basket ball, football, golf ball, squash ball.

Answer 2

Squash ball weighs 23000mg=23gm
Golf ball weighs 45gm
Basket ball weighs 0.65 kg=650gm
Football weighs 0.45kg=450gm (no data about football considered as 1 kg)
then the arrangement goes as :
basket ball, football, golf ball. squash ball
