The standard golf ball has a mass of 45g. how many golf balls are there in a bag weighing 1.8kg?

This is a working backwards question.
Since the golf ball was 45g, and the bag was 1.8kg,we need to make them the same units.
45g= 0.45kg
1.8kg= 1.8kg

Now that the units are the same, we put it in a calculator.

1.8÷0.45= 4

Therefore, there are 4 golf balls in the bags.
We can check this by doing 4×0.45= 1.8

Hope this helped!

Do something that you've always wanted to do. do something crazy, out of the ordinary but stay in your lanejaja hope it : d
