Question

The city has 28 fire engines & 36 fire trucks. find the ratio of the number of fire engines to the number of fire trucks in simplest form

Answer 1

Hi ,

According to the data given ,


number of fire engines = 28 --( 1 )

number of fire trucks = 36 -----( 2 )

Required ratio = ( 1 ) / ( 2 )

= 28 / 36

To write it in its simplest form we

have to find the HCF of 28 and 36

28 = 2 × 2 × 7

36 = 2 × 2 × 3 × 3

HCF ( 28 , 36 ) = 2 × 2 = 4

Now divide numerator and denominator

With HCF we get simplest form

Ratio = ( 28 / 4 ) / ( 36 / 4 )

= 7 / 9

I hope this helps you.
