• i still did not understand it
• For the last explanation 9 1/2 and 5 1/4. There are two dots over 9 1/2 and there is one dot over 5 1/4.
Two dots minus one dot equals to one dot.

Fractions can keep being (simplified) as long as the numerator and the denominator have a common factor by which you can divide by. There are two ways to solve this.

-----------------------------------------------------

Example:

1.

You can start at the corresponding numerators and denominators and keep dividing by a small and constant number. For this one let's choose 2. Let's simplify 28/370.

28 /2= 14

370 /2=185=not divisible by two or seven

-----------------------------------------------------

2.

For this method you need to find the GCF(the greatest common factor) To do this you should write down all of them first. Let's simplify 70/90 using this method.

Factors

70:1, 2, 5, 7, 10, 14, 35, 70
90:1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

The GCF is 10.

So, now that we have our GCF we divide the fraction by it.

70/90 divided by (/) 10 = 7/9.
