5/8*100=62.5%
2/5=1/2 5/10=1/2 1/2*1/2=1/4
.625
no, 2 over 10 simplifies to 1/5, and that isn't half. 5over 10 or 2 over 4 would equal half.
5/8+1/4 = 5/8+2/8 = 7/8
So 9/14 + 5/(-14) = 9/14 - 5/14 = 4/14 = 2/7
5 over 8 is a rational number.
There are an infinite number of them; one example is 11/16.
just double it : 10 over 28 and 20 over 56
5.5/7 ie 11/14
divide the numerator by the denominator eg.15over10=1 5over 10
5/10 = 1/2Cuz the greatest common factor(GCF) of 5 and 10 is 5.The factor of 5: 1, 5The factor of 10: 1, 2, 5 ,10
