**5. Find the difference between the place values of the two nines in 79520986**

**Solution**

The given number is 79520986

Here the place value of nine at lakhs is 9000000 and the place value of nine at hundreds is 900

Therefore required difference is 9000000 â€“ 900 = 8999100

**6. Find the difference between the place value and face value of 7 in 27650934**

**Solution**

The given number is 27650934

Here the place value of 7 in 27650934 is 70 lakhs = 70,00,000

The face value of 7 in 27650934 is 7

Therefore required difference is 70,00,000 – 7 = 69,99,993

**7. How many 6-digit numbers are there in all?**

**Solution**

The largest 6-digit number is 999999

The smallest 6-digit number is 100000

Therefore total number of 6-digit numbers = (999999-100000) + 1

=899999 + 1

=900000

=9 lakhs

**8. How many 7-digit numbers are there in all?**

**Solution**

The largest 7-digit number is 9999999

The smallest 7-digit number is 1000000

Therefore total number of 7-digit numbers = (9999999-1000000) + 1

=8999999+1

=9000000

=Ninety lakhs

**9. How many thousands make a lakh?**

**Solution**

1 lakh means 1,00,000 which is equal to one hundred thousand

**10. How many thousands make a crore?**

**Solution**

One crore=1,00,00,000 which is equal to one hundred lakh

Therefore 1,00,00,000=(10,000Ã—1000)

Hence ten thousand thousands make a crore
