pake Cara
jn ngasal.
Hitunglah hasil pengerjaan operasi hitung berikut
A. 2/5 + 175/100 – 1/4 =
2/5 + 7/4 – 1/4 =
8/20 + 35/20 – 5/20 =
43/20 – 5/20 =
38/20 = 19/10
b. 75/100 – 3/10 + 3/2 =
75/100 – 30/100 + 150/100 =
45/100 + 150/100 =
195/100 = 39/20
c. 3/2 – (2/10 + 4/5) =
15/10 – (2/10 + 8/10) =
15/10 – 10/10 =
5/10 = 1/2
d. 11 x 2/5 – 675/100 + 13/5 =
22/5 – 27/4 + 13/5 =
88/20 – 135/20 + 52/20 =
-47/20 + 52/20 =
5/20 = 1/4
Semoga membantuuuuu
