Different Number Styles

In this we will see about different number styles

. In math we have different numbers. They are natural numbers, whole numbers, rational number, fractional numbers, integers, decimal numbers, and so on. In this below we will see about example problems using different number styles. Let us see about different number styles.

Example Problems for Different Number Styles:

Example problem 1: What is |-48|?

Solution:

The absolute value of a number is its distance from 0.

On a number line, -48 is 48 units to the left of 0.

The distance between -48 and 0 is 48 units.

So, |-48| is 48.

Answer: |-48| is 48.

Example problem 2: Ethan biked '19 1/3 ' miles on Saturday and '9 2/3 ' miles on Sunday. How much farther did Ethan bike on Saturday than on Sunday?

Solution:

Find how much farther Ethan biked on Saturday by subtracting '9 2/3' from '19 1/3' .

'19 1/3 - 9 2/3 =?'

Rewrite 19 1/3, so that you can subtract.

'19 1/3 = 18 + 3/3 + 1/3 = 18 4/3'

Now subtract. Remember to subtract whole numbers from whole numbers and fractions from fractions.

'18 4/3 - 9 2/3 = 9 2/3'

This answer is in simplest form.

Ethan biked '9 2/3' miles farther on Saturday than on Sunday.

Answer: Ethan biked '9 2/3' miles farther on Saturday than on Sunday.
