Answer 1

`(10)/(50) + (35)/(50)`

Sum: [/tex] \frac{9}{10} [/tex]

Explanation:

Given,
`(1)/(5)` and
`(7)/(10)`

Expressing in an equivalent form whereby they would have a common denominator, we would multiply the numerator and denominator of each fraction by the denominator of the other fraction.

Thus, we would have:

`(1 * 10)/(5 * 10) = (10)/(50)`

`(7 * 5)/(10 * 5) = (35)/(50)`

`(10)/(50) + (35)/(50)`

The sum is:
`(10)/(50) + (35)/(50) = (10 + 35)/(50) = (45)/(50)`

Simplify

`(45)/(50) = (9)/(10)`
