Hasil dari pecahan campuran 4 2/5 + 1 2/4

1. Hasil dari pecahan campuran 4 2/5 + 1 2/4 adalah?

— Ubah ke Pecahan Biasa:

= 4 2/5

= (4 × 5 + 2)/5

= (20 + 2)/5

= 22/5

= 1 2/4

= (1 × 4 + 2)/4

= (4 + 2)/4

= 6/4

Maka:

= 4 2/5 + 1 2/4

= 22/5 + 6/4

= (22 × 4)/(5 × 4) + (6 × 5)/(4 × 5)

= 88/20 + 30/20

= (88 + 30)/20

= 118/20

= (118 ÷ 2)/(20 ÷ 2)

= 59/10

Jawaban:

$4 frac{2}{5} + 1 frac{2}{4} = 4 + 1 + frac{8 + 10}{20} \ \ = 5 frac{18}{20} : : \ \ = 5 frac{9}{10} :$
