Question

Find the sum of 0.45 and .5 using the fraction approach.

Answer 1

`(19)/(20)`

Explanation:

0.45 can be written as
`(9)/(20)` in fractional form and 0.5 can be written as
`(1)/(2)`.

Whenever adding fractions you need like bases. To do this, multiply the 0.5 fraction by 10/10. This would get you
`(10)/(20)`.

Adding fractions:

`(9)/(20) + (10)/(20)` ** only add the numerators and leave the denominator as is

=
`(19)/(20)`
