Expanded Form

Expanded form of a number is the sum of the place values of its digits.

Look at the given examples.

145 = 1 hundred + 4 tens + 5 ones = 100 + 40 + 5

182 = 1 hundred + 8 tens + 2 ones = 100 + 80 + 2

105 = 1 hundred + 5 ones = 100 + 5

193 = 1 hundred + 9 tens + 3 ones = 100 + 90 + 3

8 Write the expanded form of the following numbers.

(a) 167 = 1 hundred + 6 tens + 7 ones = + +

(b) 118 = 1 hundred + 1 ten + 8 ones = + +

(c) 125 = hundred + tens + ones = 100 + 20 + 5

(d) 156 = hundred + tens + ones = 100 + 50 + 6
