I use fractions whenever it makes the maths easier or to provide an exact result for a recurring decimal.
Examples:
* To square 15:
15 = 1.5 x 10 = 3/2 x 10
→ 15² = (3/2 x 10)² = 9/4 x 100 = 2 1/4 x 100 = 2.25 x 100 = 225
* To multiply by 5
5 = 10/2 so multiply by 10 and divide by 2.
*To divide by 5
dividing by 5 is the same as multiplying by 1/5
→ to divide by 5, multiply by 1/(10/2) = 2/10, ie double it and divide by 10.
If the result is a recurring decimal, eg what is 31 divided by 6: 31 ÷ 6 = 5 1/6 = 5.1666... (with the 6 recurring forever) only an approximate decimal can be given (5.2 or 5.17 or 5.167, etc) but the fraction gives an exact value: 5 1/6 - five and one sixth.
Eradicate the fractions.
It really depends on the type of problem you are trying to solve. Did you have a specific problem in mind?
No, you cannot use models to multiply fractions!!
We use fractions in the grocery we use fractions in the grocery shops like half a dozen
I am not sure at what you are getting at, but fractions are a math component.

It would be very difficult to teach and learn fractions if you did not use fractions!

Teachers teach fractions to their students.
step by step
People use fractions when there is slightly more or less than a whole
We use fractions when measuring at times such as when you're cooking or baking, and seeing how tall you are. :)
Use the LCM when you are adding and subtracting unlike fractions. Use the GCF when you are simplifying fractions.
