- Fill in the blanks. The first one is done for you.
Ans.
| What measure will be used to measure | 11 | 500ml | 200ml | 100ml | 50ml |
|---|---|---|---|---|---|
| 1. 750 ml of diesel- | 1 time | 1 time | 1 time | ||
| 2. 150 ml of milk | 1 time | 1 time | |||
| 3. 450 ml of water | 2 times | 1 time | |||
| 4. 1l of petrol | 1 time | ||||
| 5. 800 ml of petrol | 1 time | 1 time | 1 time | ||
| 1 l 700 ml of milk | 1 time | 1 time | 1 time |
- How many 200 ml measures of water will fill a:
(a) 1 litre measure?
(b) 2 litres measure?
Sol. (a) 1 litre = 1000 ml
No. of times = 1000/200 = 5
So, five 200 ml measures of water will fill 1 litre measure.
(b) 2 litre = 2 x 1000 ml = 2000 ml
No. of times = 2000/200 = 10
So, ten 200 ml measures of water will fill 2 litres measure.
- How many 100 ml measures of oil will fill a :
(a) 200 ml measure?
(b) 500 ml measure?
(c) 1 litre measure?
Sol. (a) No. of times = 200/100 = 2
So, two 100 ml measures of oil will fill 200 ml measure.
(b) No. of times = 500/100 = 5
So, five 100 ml measures of oil will fill 500 ml measure.
(c) No. of times = 1000/100 = 10
So, ten 100 ml measures of oil will fill 1 litre measure.
- A jar contains 1100 ml of honey. How many litres and millilitres of honey is there in the jar?
Sol. 1 litre contains 1000 ml
Therefore, 1100 ml = 1100/1000 litre = 1 litre 100 ml.
