1. 1 / 8 + 3 / 4

Penjelasan dengan langkah-langkah:

= 1/8 + 3/4

= 1/8 + 6/8

= 7/8

= 3/5 + 1/2

= 6/10 + 5/10

= 11/10

= 1 1/10

= 1/6 + 1/2

= 1/6 + 3/6

= 4/6

= 2/3

= 2/9 + 1/2

= 4/18 + 9/18

= 13/18

= 3/4 + 2/4

= 5/4

= 1 1/4

NOMOR 1.

$frac{1}{8} + frac{3}{4} = frac{(1 times 1) +(3 times 2) }{8} = frac{1 + 6}{8} = frac{7}{8}$

NOMOR 2.

$frac{3}{5} + frac{1}{2} = frac{(3 times 2) + (1 times 5)}{10} = frac{6 + 5}{10} = frac{11}{10} = 1 frac{1}{10}$

NOMOR 3.

$frac{1}{6} + frac{1}{2} = frac{(1 times 1) + (1 times 3)}{6} = frac{1 + 3}{6} = frac{4}{6} = frac{2}{3}$

NOMOR 4.

$frac{2}{9} + frac{1}{2} = frac{(2 times 2) + (1 times 9)}{18} = frac{4 + 9}{18} = frac{13}{18}$

NOMOR 5.

$frac{3}{4} + frac{2}{4} = frac{5}{4} = 1 frac{1}{4}$
