tentukan hasil operasi hitung pecahan berikut a.2/7+4/7= b. 2/3+5/6=. c.2 1/4+ 3 4/12=. d.7/8-5/6=. e. 2 1/2- 6/7=

tentukan hasil operasi hitung pecahan berikut a.2/7+4/7= b. 2/3+5/6=. c.2 1/4+ 3 4/12=. d.7/8-5/6=. e. 2 1/2- 6/7=

Jawaban:

a. 2/7+4/7 = 6/7

b. 2/3+5/6 = 4/6+5/6 = 11/6 = 1 5/6

c. 2 1/4+3 4/12 = 2 3/12+3 4/12=5 7/12

d. 7/8-5/6 = 21/24-20/24 = 1/24

e. 2 1/2-6/7 = 5/2-6/7 = 35/14-12/14 = 23/14 = 1 9/14

a. 6/7

b. 1 5/6

c. 5 7/12

d. 1/24

e. 1 9/14

semoga bermanfaat

Jawaban:

a. 6/7

b. 1 1/2

c. 5 7/12

d. 1/24

e. 1 9/14

Penjelasan dengan langkah-langkah:

$frac{2}{7} + frac{4}{7} = frac{6}{7} \$

Jika penyebutnya sama, langsung jumlahkan saja

$frac{2}{3} + frac{5}{6} = frac{4 + 5}{6} = frac{9}{6} div frac{3}{3} = frac{3}{2} = 1 frac{1}{2} \$

$2 frac{1}{4} + 3 frac{4}{12} = frac{9}{4} + frac{40}{12} = frac{27 + 40}{12} = frac{67}{12} = 5 frac{7}{12} \$

$frac{7}{8} - frac{5}{6} = frac{21 - 20}{24} = frac{1}{24} \$

$2 frac{1}{2} - frac{6}{7} = frac{5}{2} - frac{6}{7} = frac{35 - 12}{14} = frac{23}{14} = 1 frac{9}{14} \$

Semoga membantu dan sukses selalu 🙂
