1. hasil dari 2,86 - 1 5/8 adalah.........
2.hasil dari 65% : 7/10 : 3 tiga / 7 adalah......
3. hasil dari 2,32 m kubik - 6000 cc +400 l .....................dm kubik

Answer 1

1. 2,86 - 1 5/8 = 2,235
2 13/6

Answer 2

1)
2,86 - 1 5/8
= 2,86 - 1,625
= 1,235

2)
65% : 7/10 : 3 3/7
= 65/100 : 7/10 : 24/7
== 65/100 x 10/7 x 7/24
= 65/240
= (65:5)/(240:5)
= 13/48

3)
2,32 m^3 - 6.000 cc+ 400 L
= (2,32x1.000) dm^3 - (6.000:1.000) dm^3 +
400 dm^3
= 2.320 dm^3 - 6 dm^3 + 400 dm^3
= 2.314 dm^3 + 400 dm^3
= 2.714 dm^3
