Question

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

Answer 1

Is it 400?

Answer 2

\[1.8kg \times{1000 g \over 1kg} \times {1 ball \over 45g}\]

Answer 3

wait no is it 40?

Answer 4

yes 40 balls

Answer 5

\[\large \bf 1~ball~weigh~45g=0.045kg\]
so,
\[\large \bf 1kg~weigh=\frac{1}{0.045}~balls\]
but we have to find out,1.8 kg,so
\[\large \bf 1.8kg~weigh=\frac{1}{0.045} \times 1.8=40~balls=\color{red}{ANSWER}\]
