9)
1 book - 7.5 / 3 = 2.5
50books - 2.5 x 50 = 125
125cm = 1.25m
ans: 1.25m

10)
1 step - 12 / 30 = 0.4
1750 steps - 1750 x 0.4 = 700m
700m = 0.7km
ans: 0.7km

11)
1 pail - 17280 / 12 = 1440
75pails - 1440 x 75 = 108000
108000ml = 108l
ans: 108l

12)
1 day - 23500 / 7 (round off) = 33571.1ml
ans: 3357.1ml

Page 36 Challenging Practice
1)
1/2(one-half) - 1/3(one-third) = 1/6 (one-sxth)
1/6(one sixth) - 325ml
325 x 60 = 1950ml
1950ml = 1.95l
ans: 1.95l

2)
1.53 x 1000 = 1530g
1530 - 650 =880g
880g / 4 = 220g
220g x 3 = 660g
660g = 0.66kg
ans: 0.66kg

Page 37 Problem Solving
1)
5700ml - 1200ml = 4500ml
4500ml / 3 = 1500ml
1500ml / 3 = 500ml
5700ml - 500ml = 5200ml
5200ml = 5.2l
ans: 5.2l

2) use listing method
0.1km = 100m
Session Distance
1 800m
2 900m
3 1000m
4 1100m
5 1200m
6 1300m
7 1400m
8 1500m
9 1600m

ans: 1600m
