Bunny and Banno Celebrate their Wedding Anniversary.

Do you remember the wedding in Bunny's family last year? (See Math-Magic Class III page 153). Bunny and Banno decided to have a party one year after their wedding.

Animals celebrating Bunny and Banno's wedding anniversary. Some of them have small buckets in their hands.

They invited their family and friends. They made a special sweet dish — kheer, which is made by cooking milk, sugar and rice together.

All the animals came — running, hopping and even crawling!

Long Live! Bunny and Banno

The elephant is drinking 50 litres of kheer.

The giraffe is drinking__litres.

The cow is drinking__litres.

Then came the squirrel. She said — I can't drink 1 litre of kheer, please give me only 500 millilitres.

The donkey asked — 500 millilitres of kheer? Isn't that more than a litre?

The fox said — Come on, don't behave like a donkey! One litre is 1000 millilitres, so 500 millilitres is half a litre.

The frog hopped along with nine other friends. He said — Oh, we only want 100 millilitres each!

10 dancing frogs.

OK., here is your kheer — said the cat, while serving the kheer. She took 10 glasses and poured 100 millilitres kheer in each glass.

The donkey looked confused and asked — Ten glasses of 100 mL each. How much is that?

The fox got another chance to show off ! He said — Ah, That is

simple! 10 times hundred millilitres is ___________ millilitres = litre.

Now you write it 10x 100 mL=

Few grasshoppers and ants asking," Are we late?"

Look, a group of ants is marching here! — the grass hoppersaid.

The kheer is finished. Now whatcanwedo? —thecatsaid sadly.

Don't worry, they won't drink much. Each of them will take only one millilitre. That is all. I will share my kheer with them — the elephant said and wiped the cat's tears with his ear.

How many are you all together? — the elephant asked.

We are only one thousand — said the ants.

The cat said — Oh no, one thousand! We have to give kheer to

1000 ants!

After thinking the elephant said — No problem, I can manage.

Each ant drinks 1 millilitre of kheer.

So, 1000 ants drink: 1000 x 1 mL =___mL.

Ah! they will need the same as the ten frogs — said the donkey.

All the ants drank the kheer. Everyone was happy. They sang and danced to celebrate the wedding anniversary.
