Penjelasan dengan langkah-langkah:

Nomor G

$= 1 frac{5}{7} + 2frac{2}{3}$

$= (1 + 2 ) + ( frac{5}{7} + frac{2}{3} )$

$= 3 + ( frac{5 times 3 + 2 times 7}{21} )$

$= 3 + frac{15 + 14}{21}$

$= 3 + frac{29}{21}$

$= 3 + 1 + frac{8}{21}$

$= 4 + frac{8}{21}$

$= 4 frac{8}{21}$

$:$

Nomor H

$= 2 frac{5}{8} + 1 frac{1}{6}$

$= (2 + 1) + ( frac{5}{8} + frac{1}{6} )$

$= 3 + frac{5 times 3 + 1 times 4}{24}$

$= 3 + frac{15 + 4}{24}$

$= 3 + frac{19}{24}$

$= 3 frac{19}{24}$

$:$

Nomor I

$= 3 frac{3}{10} + 2 frac{3}{8}$

$= (3 + 2 ) + ( frac{3}{10} + frac{3}{8} )$

$= 5 + frac{3 times 4 + 3 times 5}{40}$

$= 5 + frac{12 + 15}{40}$

$= 5 + frac{27}{40}$

$= 5 frac{27}{40}$

Jawaban:

g. 6 5/7

h. 3 19/24

i. 6 1/2

Penjelasan dengan langkah-langkah:

g. 1 5/7 + 2 2/3

= 12/7 + 8/3

= 12 × 3/7 × 3 + 8 × 7/3 × 7

= 92/21

= 4 8/21

h. 2 5/8 + 1 1/6

= 21/8 + 7/6

= (21 × 3)/(8 × 3) + (7 × 4)/(6 × 4)

= 63/24 + 28/24

= 91/24

= 3 19/24

i. 3 3/10 + 2 3/8

= 33/8 + 19/8

= 52/8

= 52 ÷ 4/8 ÷ 4

= 12/2

= 6 1/2
