Question

Use properties of rational numbers to multiply the following.

6/7 x 42.21

Answer 1

The value of
`(6)/(7) * 42.21`= 36.18

Explanation:

We have,

`(6)/(7) * 42.21`

To find, the value of
`(6)/(7) * 42.21` = ?

∴
`(6)/(7) * 42.21`

=
`(6)/(7) * (4221)/(100)`

We know that,

The properties of rational numbers,

`(a)/(b) * (c)/(d) =(a* c)/(b* d)`

=
`(6* 4221)/(7* 100)`

=
`(25326)/(700)`

= 36.18

Thus, the value of
`(6)/(7) * 42.21`= 36.18
