2/5 + 0,65 + 45%= 1 1/6 + 2,2 – 55% = 35% +1 1/5 – 0,8 =

Penjelasan dengan langkah-langkah:

1. 2/5 + 0,65 + 45% =

2/5 = 2/5 x 100% = 2 x 20 = 40%

0,65 = 0,65 x 100% = 65%

40% + 65% + 45% = 150%

2.1 1/6 + 2,2 – 55% =

1 1/6 = 7/6 = 116,6%

2,2 = 220%

116,6 + 220% – 55% = 281,6%

3. 35% + 1 1/5 – 0,8 =

1 1/5 = 6/5 = 120%

0,8 = 80%

35% +  120% – 80% = 75%
