Question

Guys help what is 10/100 + 7/10

Answer 1

Answer:
`(4)/(5)`

Step-by-step explanation: The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(
`(10)/(100)`,
`(7)/(10)`) = 100

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(
`(10)/(100)`×
`(1)/(1)`)+(
`(7)/(10)`×
`(10)/(10)`)=?

Complete the multiplication and the equation becomes

`(10)/(100)`+
`(7)/(10)`=?

The two fractions now have like denominators so you can add the numerators.

Then:

`(10+70)/(100)`=
`(80)/(100)`

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 80 and 100 using

GCF(80,100) = 20

`(80÷20)/(100÷20)`=
`(4)/(5)`

Therefore:

`(10)/(100)`+
`(7)/(10)`=
`(4)/(5)`
