Multiplication of decimals by a whole number

# Multiplication of decimals by a whole number

#### Question 1

A flea can jump up to 200 times its body length.

The body length of the flea is 2.5 mm.

What is the furthest distance the flea can jump?

#### Solution

The body length of the flea is 2.50 mm.

The flea can jump 200 times this length.

200 × 2.5 | = 2 × 2.5 × 100 |

= 5 × 100 | |

= 500. |

Therefore the furthest distance the flea can jump is 500 mm.
