4/20 = 2/10 = 1/5
20/5 = 4
It is 3 over 4.
It's a way to reduce fractions. If you wanted to reduce 20/24 and you knew that the GCF of 20 and 24 was 4, you would divide 20 and 24 by 4 and get 5 and 6. 20/24 = 5/6
6√20 First we reduce the 6 and 3 so we get 2√20 Then we reduce the 20 and 53√5 `````````````````````````````````√5so we get 2√4 We know that √4 is 2 so by substituting, we get 2x2 which is 4.
Divide both by four. The answer is five.

Example 2/4 + 4/5 convert that to 2/4 = 10/20 4/5 = 16/20 10/20 + 16/20 = 26/ 20, reduce that to 13/10
0.75
Since both numbers will divide exactly by four, 16/20 reduces to 4/5
20/12 = 5/3 by dividing the numerator and denominator by their HCF which is 4

When you reduce a mixed number, the whole number does not change. It is the fraction that changes. For insance, if you want to reduce 5 and 3/6, you would simply keep the 5 and reduce the 3/6 to 1/2. The final outcome would be 5 and 1/2. 20 and 15/20 would reduce to 20 and 3/4. 17 and 10/12 would reduce to 17 and 5/6. And so on...
