Question

-3/10+7/3=I have to simplify these( I'm awful with fractions, I have a whole packet but these are my most confused ones)3/3 - 5/4=- 5/9 - 1/9=3/6-5/6=5/8 - 7/8

Answer 1

`(-3)/(10)+(7)/(3)=(-3\cdot3+7\cdot10)/(10\cdot3)=(-9+70)/(30)=(61)/(30)`
`(3)/(3)-(5)/(4)=(3\cdot4-5\cdot3)/(3\cdot4)=(12-15)/(12)=(-3)/(12)=(-1)/(4)`
`(-5)/(9)-(1)/(9)=(-5-1)/(9)=(-6)/(9)=(-2)/(3)`
`(3)/(6)-(5)/(6)=(3-5)/(6)=(-2)/(6)=(-1)/(3)_{}`
`(5)/(8)-(7)/(8)=(5-7)/(8)=(-2)/(8)=(-1)/(4)`
