The numerator is_______.
The denominator is________.


Hint: the numerator isn't 25; I need this ASAP. Thank you☺️

Answer 1

`\implies {\blue {\boxed {\boxed {\purple {\sf {Numerator\:=\:25 }}}}}}`

`\implies {\blue {\boxed {\boxed {\purple {\sf {Denominator \:=\:56}}}}}}`

`\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}`

`\: ( - 3)/(7) + (7)/(8)`

Since the denominators are unequal, we find the L.C.M (lowest common multiple) for both denominators.

The L. C. M for 7 and 8 is 56.

Now,

➺
`\: ( - 3 * 8)/(7 * 8) + (7 * 7)/(8 * 7)`

➺
`\: ( - 24)/(56) + (49)/(56)`

Now that the denominators are equal, we can add them.

➺
`\: ( - 24 + 49)/(56)`

➺
`\: ( 25)/(56)`

Therefore, the numerator is
`\boxed{ 25 }` and the denominator is
`\boxed{ 56 }`.
