Answer :
Let's break down each of these questions step-by-step. These questions are related to understanding large numbers and their relationships in terms of the number system commonly used in countries like India.
b) How many thousands make 1 lakh?
In the Indian numbering system, a 'lakh' is equal to 100,000. If you know that 1 thousand is equal to 1,000, then:
[tex]\frac{100,000}{1,000} = 100[/tex]
So, 100 thousands make 1 lakh.
c) How many lakhs make 1 crore?
A 'crore' is equal to 10,000,000. Since 1 lakh is 100,000, you can find out how many lakhs are in a crore by dividing:
[tex]\frac{10,000,000}{100,000} = 100[/tex]
This means that 100 lakhs make up 1 crore.
d) How many crores make 1 arab?
An 'arab' is equal to 1,000,000,000. To determine how many crores make an arab, since 1 crore is 10,000,000:
[tex]\frac{1,000,000,000}{10,000,000} = 100[/tex]
Therefore, 100 crores make up 1 arab.
e) How many lakhs are there in 1 million?
A million is equal to 1,000,000. Since a lakh is 100,000:
[tex]\frac{1,000,000}{100,000} = 10[/tex]
So, there are 10 lakhs in 1 million.
f) How many millions are there in 1 crore?
We know that 1 crore equals 10,000,000. Given that 1 million is 1,000,000:
[tex]\frac{10,000,000}{1,000,000} = 10[/tex]
Thus, there are 10 millions in 1 crore.
g) How many crores are there in 100 million?
Considering that 1 crore amounts to 10,000,000, you then have 100 million equating to:
[tex]\frac{100,000,000}{10,000,000} = 10[/tex]
Hence, 10 crores are found in 100 million.
h) How many billions are there in 1 arab?
Reminding ourselves that 1 arab is indeed 1,000,000,000 and 1 billion is similarly valued:
[tex]\frac{1,000,000,000}{1,000,000,000} = 1[/tex]
Therefore, there is 1 billion in 1 arab.
These calculations are helpful in understanding the similarities and differences between the Indian and Western numbering systems and in converting between these numerals.
