Soal Jawaban Kurikulum Merdeka

Tentukan hasil operasi hitung berikut.

a.0,5 x 2/7

b.-2/3/ +0,8 x 0,3

c.1,6 : (-0,8) + 2/5

d.2,6 x 4/7 + 2/5


Jawaban

a.0,5 x 2/7 = ½ x 2/7 = 1/7


b.-2/3/ + 0,8 x 0,3 = -2/3 + 8/10 x 3/10 = -2/3 + 24/100 = -200/300 + 72/300 = -128/300 = -32/75

c.1,6 : (-0,8) + 2/5 = 16/10 : (-8/10) + 2/5 = 162/10 x (-10/8) + 2/5 = -2/1 + 2/5 = -10/5 + 2/5 = -8/5


d.2,6 x 4/7 + 2/5 = 26/10 x 4/7 + 2/5 = 104/70 + 2/5 = 104/70 + 28/70 = 132/70 = 1 62/70 = 1 31/35
