PENYELESAIAN :

= 3 9/4 + 7 1/2

= 21/4 + 15/2

= 21 + 30/4

= 51/4

= 12 3/4

Penjelasan dengan langkah-langkah:

$color{cyan}{tt{ 3 frac{9}{4} + 7frac{1}{2}}} \ sf frac{21}{4} + frac{15}{2} \ sf frac{21 times 2}{4 times 2} + frac{15 times 4}{2 times 4} \ sf frac{42}{8} + frac{60}{8} = frac{42 + 60}{8} = frac{102}{8} = frac{51}{4} = 12 frac{3}{4}$
