2/4 × 5/8 : 4/7 =1/4 + 1/2 - 2/5 =1/6 × 2 1/4 : 5 1/8 =

2/4 × 5/8 : 4/7 =1/4 + 1/2 – 2/5 =1/6 × 2 1/4 : 5 1/8 =

1 .2/4 × 5/8 ÷ 4/7

= 10/32 ÷ 4/7

= 10/32 × 7/4

= 70/128

= 35/64

2. 1/4 + 1/2 – 2/5

= 5/20 + 10/20 – 8/20

= 7/20

3. 1/6 × 2 1/4 ÷ 5 1/8

= 1/6 × 9/4 ÷ 41/8

= 9/24 ÷ 41/8

= 9/24 × 8/41

= 72/984

= 9/123

= 3/41

Penjelasan dengan langkah-langkah:

$frac{2}{4} times frac{5}{8} div frac{4}{7}$

$frac{2}{4} times frac{5}{8} times frac{7}{4}$

$frac{10}{32} times frac{7}{4}$

$frac{70}{128} = frac{35}{64}$

$frac{1}{4} + frac{1}{2} - frac{2}{5}$

$frac{5}{20} + frac{10}{20} - frac{8}{20}$

$frac{15}{20} - frac{8}{20}$

$frac{7}{20}$

$frac{1}{6} times 2 frac{1}{4} div 5 frac{1}{8}$

$frac{1}{6} times frac{9}{4} div frac{41}{8}$

$frac{1}{6} times frac{9}{4} times frac{8}{41}$

$frac{9}{24} times frac{8}{41}$

$frac{72}{984}$

$frac{12}{164} = frac{6}{82} = frac{3}{41}$
