Q.(1/5)

Q.(1/5)

7/4 + 14/8

= 7/4 + 14/8

= 7/4 + 7/4

= 14/4

= 7/2

= 3 1/2

90/10 – 180/20

= 90/10 – 180/20

= 9 – 9

= 0

2/6 × 2/3

= 2/6 × 2/3

= 1/3 × 2/3

= 2/9

Penjelasan dengan langkah-langkah:

$frac{7}{4} + frac{14}{8} \ = frac{7}{4} + frac{14}{8} \ = frac{7}{4} + frac{7}{4} \ = frac{7 + 7}{4} \ = frac{14}{4} \ = frac{7}{2} \ = 3frac{1}{2}$

________________

$frac{90}{10} - frac{180}{20} \ = (90 div 10) - (180 div 20) \ = 9 - 9 \ = 0$

________________

$frac{2}{6} times frac{2}{3} \ = frac{2}{6} times frac{2}{3} \ = frac{1}{3} times frac{2}{3} \ = frac{1 times 2}{3 times 3} \ = frac{2}{9}$
