**Que-4: Find the difference between the place-values of two sixes in 6,56,348.**

**Solution- **The number is: 6,56,348

The first six is in the ten-thousands place, and the second six is in the units place.

So, the place-values of the two sixes are:

Six at the thousands place: 6×1,000 = 6,000

Six at the one-lakhs place: 6 x 1,00,000 = 6,00,000

The difference between these place-values is:

6,00,000−6,000 = 5,94,000 Ans.

**Que-5: ****Find the difference between the place-value and the face-value of 8 in the numerical 5,86,273.**

**Solution- **Place value of 8 = 8×10,000 = 80,000

Face value of 8 = 8

Difference 80,000 – 8 = 79,992

Hence the difference between place value and the face value of 8 is 79,992

**Que-6: Write each of the following in expanded form :**

**(i) 5,16,287**

**(ii) 13,25,694**
