3/4 + 12/20 + 6/8 + 7/8 + 1/4 =

3/4 + 12/20 + 6/8 + 7/8 + 1/4 =

JAWABAN:

= 3/4 + 12/20 + 6/8 + 7/8 + 1/4

= 30/40 + 24/40 + 30/40 + 35/40 + 10/40

= 54/40 + 65/40 + 10/40

= 54/40 + 75/40

= 129/40

MAAF KALAU SALAH

Penjelasan dengan langkah-langkah:

$= frac{3}{4} + frac{12}{20} + frac{6}{8} + frac{7}{8} + frac{1}{4} \ = frac{4}{4} + frac{12}{20} + frac{6}{8} + frac{7}{8} + frac{1}{4} \ = 1 + frac{12}{20} + frac{6}{8} + frac{7}{8} + frac{1}{4} \ = 1 + frac{12}{20} + frac{13}{8} \ = 1 + frac{3}{5} + frac{13}{8} \ = frac{129}{40} = 3 frac{9}{40}$
