It is 3 over 4.
15% means fifteen over one hundred ( 15/100) 15/100 Cancel down by '5' 3/20 This will not reduce any further as '3' is NOT a factor of '20'.
no
No.
15 over 25 reduces to 3 over 5
20/5 = 4
No; 7 / 20 is irreducible.
15/20, or 15 over 20 is 15 ÷ 20 = 3/4 = ¾
Yes.
Yes.
No, not all of those fractions are equivalent. 5/20 reduces to 1/4. 8/40, 3/15, and 6/30 reduce to 1/5, so they are equivalent.
No you can not. 15 and 41 do not have a common factor
It is: 20/36 = 5/9
