need to know what's the addition in the following fraction​

Answer 1

$\huge\underline\mathcal\green{...Answer...}$

$\huge\sf{ \frac{4}{5} + \frac{9}{10} }$

LCM of 5,10 is 10

Rough work ->

${ \frac{4}{5} \times 10}$

${ = 8}$

And

${ \frac{9}{10} \times 10}$

$= 9$

Fair work –>

$\huge\sf{ \frac{8 + 9}{10} }$

$\huge\sf{ \frac{17}{10} }$

Hence ,17/10 is your answer.

Answer 2

Your answer:-

$= \frac{4}{5} + \frac{9}{10}$

$lcm \: of \: 5 \: and \: 10 \: is \: 10.$

$= \frac{4 \times 2}{5 \times 2} + \frac{9 \times 1}{10 \times 1}$

$= \frac{8}{10} + \frac{9}{10}$

$= \frac{8 + 9}{10}$

$= \frac{17}{10}$
