Question

(1 4/7)_____-(15/21)

Answer 1

(1 4/7)

_____

-(15/21)​

To solve;

we will cange the division to multiplication. By doing that 15/21 becomes 21/15

That is;

`(14)/(7)*-(21)/(15)`

7 can divide 21 to give 3

Hence;

`(14)/(1)*-(3)/(15)`

3 can also divide 15 to give 5

`(14)/(1)*-(1)/(5)`

we will now multiply

`=(-14)/(5)`
`=-2(4)/(5)`
