Hi…

Q.

~ Nomor Satu

$frac{5}{10} + frac{14}{25}$

$frac{5 times 5}{10 times 5} + frac{14 times 2}{25 times 2}$

$frac{25}{50} + frac{28}{50}$

$frac{25 + 28}{50}$

$frac{53}{50}$

$1frac{3}{50}$

~ Nomor Dua

$frac{9}{18} - frac{8}{14}$

$frac{9 times 14}{18 times 14} - frac{8 times 18}{14 times 18}$

$frac{126}{252} - frac{144}{252}$

$frac{126 - 144}{252}$

$- frac{18}{252} div frac{3}{3}$

$- frac{6}{84} div frac{6}{6}$

$- frac{1}{14}$

Jawab:
1. 53/50
2. 1/14

Penjelasan dengan langkah-langkah:
1. = $frac{ ( 5 X 2 ) + ( 14 X 10 )}{10 X 25}$ = $frac{625}{250}$ dibagi 5 atas bawah untuk menyerdehanakan
= 53/50
2. = $frac{ ( 9 X 14 ) - ( 8 X 18 ) }{18 X 14}$ = $frac{-18}{252}$ atas bawah dibagi 18
= 1/14
