Question

Find 4 1/5 - 7 2/3
28 2/15
28 3/10
32 1/5
323/5

Answer 1

Final answer is
`=3(7)/(15)`.

Explanation:

`4\ (1)/(5)-7\ (2)/(3)`

`=(4\cdot5+1)/(5)-(7\cdot3+2)/(3)`

`=(20+1)/(5)-(21+2)/(3)`

`=(21)/(5)-(23)/(3)`

`=(21)/(5)\cdot(3)/(3)-(23)/(3)\cdot(5)/(5)`

`=(63)/(15)-(115)/(15)`

`=-(52)/(15)`

`=-3(7)/(15)`

Hence final answer is
`=3(7)/(15)`.
