Divide both by four. The answer is five.
20/5 = 4
It is 3 over 4.
4/9
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.
20/12 = 5/3 by dividing the numerator and denominator by their HCF which is 4
Since both numbers will divide exactly by four, 16/20 reduces to 4/5
No.
No; 7 / 20 is irreducible.
4/20 = 2/10 = 1/5
It is: 20/36 = 5/9
1/10
10/20 reduces to 1/2.
