today i am a lot happy cause in my english exam i got 70+ marks out of 80!!​

Answer 1

Step-by-step explanation:

$\bf \: LCM \: of \: 7and \: 9 = 63 \\ \sf \frac{4}{7} = \frac{4 \times 9}{7 \times 9} = \frac{36}{63} \\ \sf \frac{8}{9} = \frac{8 \times 7}{9 \times 7} = \frac{53}{63} \\ \\ \sf \frac{36}{63} + \frac{53}{63} = \frac{36 + 53}{63} = \frac{92}{63} \\ \sf \therefore \: \frac{4}{7} + \frac{8}{9} = \frac{92}{63} \\ \bf in \: mixed \: form \: = 1 \frac{29}{63}$

Hope it helps :-)

Answer 2

Answer:

$\frac{8}{9} + \frac{4}{7}$

We can't add two fractions with different denominators (the bottom number). So you need to get a common denominator - both bottom numbers need to match. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 8 by 7, and get 56, then we multiply 9 by 7 and get 63.

Do the same for the second term. We multiply 4 by 9, and get 36, then multiply 9 by 7 and get 63.

On solving, we get

$\frac{92}{63}$

Hope that helps you Jinie

uwu congratulations! :)
