Question

Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator

0.30 cm to 0.42 cm​

Answer 1

`(5)/(7)`

Explanation:

Given numbers are :

0.30 cm and 0.42 cm

We need to find the ratio of the above whole numbers.

Taking 0.3 cm on the numerator and 0.42 cm on the denominator. So,

`(0.3)/(0.42)=((3)/(10))/((42)/(100))\\\\=(3)/(10)* (100)/(42)\\\\=(10* 3)/(42)\\\\=(10)/(14)\\\\=(5)/(7)`

So, the required fraction is equal to
`(5)/(7)`.
