Nilai dari a+c/b jika diketahui nilai a: 1 3/4, b: 12/5,dan c : 20 4/5

Nilai dari a+c/b jika diketahui nilai a: 1 3/4, b: 12/5,dan c : 20 4/5

$a + frac{c}{b} \ = 1 frac{3}{4} + frac{20 frac{4}{5} }{ frac{12}{5} } \ = frac{7}{4} + frac{ frac{104}{5} }{ frac{12}{5} } \ = frac{7}{4} + frac{104}{5} times frac{5}{12} \ = frac{7}{4} + frac{520}{60} \ = frac{105 + 520}{60} \ = frac{625}{60} = 10 frac{25}{60} = 10 frac{5}{12}$

A + c/b =
a + c ÷ b =
1 3/4 + 20 4/5 ÷ 12/5 =
7/4 + 104/5 x 5/12 =
7/4 + 104/12 =
21/12 + 104/12 =
125/12 =
10 5/12
