**My Litre Bottle**

**Collect a 1-litre bottle and some other small bottles. Guess how many times you have to pour from each of the small bottles to fill the litre bottle. Check if your guess is correct and fill in the table.**

Bottles | My guess | My measure |
---|---|---|

Bottles 1 | ||

Bottles 2 | ||

Bottles 3 |

Sol. As the understanding capacity of each person is different from one another. Thus, the measurements may and may not be the same.

Bottles | My guess | My measure |
---|---|---|

Bottles 1 | 200 ml | 190 ml |

Bottles 2 | 1000 ml | 900 ml |

Bottles 3 | 1 L | 1.5 L |

**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
