Exercise 22 Page 15

For a decimal number, the whole number part tells us how many whole units we will move away from 0 along the number line. The fractional part expresses how much of the next whole unit will be included.

To graph the given number on a number line, let's first consider its form. 4.8

In this case, we are given a decimal number. A decimal number is a number whose whole number part and fractional part are separated by a decimal point. 4. 8 The whole number part tells us how many whole units we will move away from 0 along the number line. The fractional part expresses how much of the next whole unit will be included. Since we have a positive number, we will move to the right 4 whole units, and then 810= 45 units further.
