Question

Simplify the expression below.
7
/100 +
9/
100

Answer 1

Answer: 4/25

Explanation:

Since the fractions have a common denominator, we can just add the numerators:

`\sf{\cfrac{7}{100}+\cfrac{9}{100}}`

`\sf{\cfrac{7+9}{100}}`

`\sf{\cfrac{16}{100}}`

Reduce to lowest terms by dividing by 4.

`\sf{\cfrac{4}{25}}`

Therefore, the answer is 4/25.

Answer 2

`(4)/(25)`

Explanation:

`(7)/(100)` +
`(9)/(100)`

since denominators are the same , then add numerators , leaving the denominator as 100

=
`(7+9)/(100)`

=
`(16)/(100)` ( divide numerator/ denominator by 4, the highest common factor )

=
`(16/4)/(100/4)`

=
`(4)/(25)`
