Question

A boy 1m tall looks at the swimming pool, which appears to be 75 cm deep, according to the people around him. He finds himself almost completely submerged in water when he steps into the water. Was he tricked? How did it happen?

Answer 1

Well the answer is:

No he was not tricked.

This is what happened:

He is 1 meter tall and the water is 75 cm deep.

Let's convert the units so that they are the same we can look at it two ways.

1 meter (m) = 100 centimeters (cm)

This means that just about 75% of his body would be submerged.

You can also convert it 75 centimeters into meters.

75 centimeters = 0.75 meters.

Just remember that centi means 100th of a unit or $\dfrac{1}{100}$.
