Question #314ba

Answer 1

`0.183` of 3 Km

Explanation:

When you set up a ratio or fraction it is defined by the total, in this case the part is `550 m` and the whole is `3 Km`.

First as always we have to compare apples with apples, in this case we either have to convert `550 m` to Km or the `3 Km` to m.

I liked the second so `3 Km = 3000 m`

the fraction is `(550 m) / (3000 m) = 0.183`

The other way would be `550 m = 0.55 Km`

`(0.55 Km)/(3 Km) = 0.183`

Answer 2

`550/3000 = 11/60`

Explanation:

When you write a fraction you are showing :

`("part")/("whole")`

In order to do this the units have to be the same, so you can write `3km` as `3000m`

`550m` is the 'part' and `3000m` is the 'whole'.

The fraction is : `(550m)/(3000m)`

Note:

• the units are the same, so they will cancel.
  The fraction does not have a unit, it merely indicates how the two quantities compare with each other.

• 'fraction' generally refers to a common fraction.

• fractions should be given in the simplest form, Divide the numerator and denominator by the highest common factor

`(550 div 50)/(3000 div 50) = 11/60`
