Hitunglah hasil pengerjaan operasi hitung berikut

$a. : frac{2}{5} + 1.75 - frac{1}{4} = \ \ \ b. : 75% - 0.3 + 1 frac{1}{2} = \ \ \ c. : 1 frac{1}{2} - (0.2 + frac{4}{5} ) = \ \ \ d. : 11 times frac{2}{5} - 6.75 + 2 frac{3}{5} =$

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
