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

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
