Question

Whats the value of 8 1/10 divided by 4 1/5

Answer 1

1
`(39)/(42)`

Explanation:

The first step is to change the mixed numbers to improper fractions

8
`(1)/(10)` =
`(81)/(10)` and

4
`(1)/(5)` =
`(21)/(5)`

We now have

`(81)/(10)` ÷
`(21)/(5)`

To perform the division.

Leave the first fraction

Change division to multiplication

Turn the second fraction upside down

Simplify if possible

Hence

`(81)/(10)` ×
`(5)/(21)` ← cancel the 5 and 10

=
`(81)/(2)` ×
`(1)/(21)`

=
`(81(1))/(2(21))`

=
`(81)/(42)` = 1
`(39)/(42)`
