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!
