Question

What is the simplest form for 21/18

Answer 1

Divide both the numerator and denominator by 3.

21 / 3 = 7
18 / 3 = 6

Therefore the simplest form is 7/6.

Answer 2

What is the simplest form of
`(21)/(18)`?

You must find the GCF

Look at the factors of 21:

1,3,7,21

Look at the factors of 18:

1,2,3,6,9,18

Look at the common factors

1,3

So 3 is the GCF

Now divide
`(21)/(18)`by
`(3)/(3)`=
`(7)/(6)`


`(7)/(6)` can be changed to a mix fraction. Divide the numerator(the top-7) by the denominator(bottom-6)

7÷6=
`1 (1)/(6)`

Answer:


`(7)/(6)` or
`1 (1)/(6)`
