Understanding Multiplication by Multiples of 100

The Property of Multiplying by 101

• Multiplying a number by 101 can be simplified by breaking it down.

• Notice that 101 can be expressed as 100 + 1.

• Therefore, multiplying any number 'x' by 101 is the same as:

  • (x * 100) + (x * 1)

• This means you multiply the number by 100 and then add the original number itself.

Applying the Rule to the Given Problem

• In this case, the number is 48.

• So, 48 * 101 = (48 * 100) + (48 * 1)

• Calculate the first part: 48 * 100 = 4800

• Calculate the second part: 48 * 1 = 48

• Add the results: 4800 + 48 = 4848
