Some Big, Big Numbers!

1.In the Class IV Math-Magic you heard of the number ‘lakh’ which is equal to a hundred thousand. You had read that there Eire about one lakh brick kilns in our country, where bricks Eire made.

(а)What other things have you heard of in lakhs?

Ans. I have heard of following things in lakhs:

•Population of town

•Number of vehicles on the road.

•Number of shops in a city.

•Number of workers in an industrial township.

(b)Write the number one thousand. Now write one hundred thousand. So how mEiny zeroes are there in the number one IEIMI? Easy, isn’t it?

Ans. One thousEind = 1000

One hundred thousand = 100000 There are 5 zeroes in one lsikh.

 

(c)There Eire about two lakh boats in our country. Half of them are without a motor. What is the number of boats with a motor? Write it.

Ans. Total number of boats = 2 lakh

Number of boats without motor = 2/2 = 1 lakh Number of boats with motor = 2-1 = 1 lsikh

(d)About one fourth of the boats with a motor Eire big machine boats. How many thousand machine boats Eire there? Come on, try to do it without writing down.

Ans. Number of motor boats = 100000

1/4 x 100000 = 25000

Hence, number of machine boats = 25000 (twenty five thousand)
