Question

Enter the value of 4 1/4 - 5/7 + (-2/7) - (-3)

Answer 1

`=6(1)/(4)`

Explanation:

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

`4(1)/(4)=(4\cdot 4+1)/(4)`

`=(17)/(4)`

`=(17)/(4)-(5)/(7)+\left(-(2)/(7)\right)-\left(-3\right)`

`=(99)/(28)+\left(-(2)/(7)\right)-\left(-3\right)`

`=(99)/(28)-(2)/(7)-\left(-3\right)`

`=(13)/(4)-\left(-3\right)`

`=(13)/(4)+3`

`=(25)/(4)`

`(25)/(4)=6(1)/(4)`

`=6(1)/(4)`
