Question

5+7/9+4/12
Someone tell me the ans pls

Answer 1

55/9

Explanation:

`5+\frac79+(4)/(12)=\frac51+\frac79+(4)/(12)`

We need to make the denominators the same:

`\implies(5* 36)/(1* 36)+(7* 4)/(9* 4)+(4* 3)/(12* 3)=(180)/(36)+(28)/(36)+(12)/(36)`

Now simply add the numerators:

`\implies (180)/(36)+(28)/(36)+(12)/(36)=(220)/(36)`

Simplify by reducing:

`\implies (220)/(36)=(55)/(9)`

Solution as a mixed number:
`6\frac19`
