Question

Write 70 cm as a fraction of 2.1 m

Answer 1

`(1)/(3)`

Explanation:

We require the quantities to have the same dimensions.

Using the conversion

1 metre = 100 cm, then

2.1 m = 2.1 × 100 = 210 cm

The fraction can then be expressed as

`(70)/(210)` ← divide numerator/ denominator by 70

=
`(1)/(3)` ← in simplest form
