20, although if you reduced 15/20 to 3/4, the common denominator would be 4.
no 4 is not a factor of 15 because 4 times 3 is 12 and 4 times 5 is 20
Simplest form of 15 over 20 is 3/4.
3 x 1/2 = 3/2 or 6/4. If you're adding 7/4 and 3/4 to that, the answer is 16/4, which equals 4.
3 over 4 is less than 4 over 5. 3 over 4 is equal to .75 and 4 over 5 is equal to .80.80>.75
3/4 * 1/20 = (3*1)/(4*20) = 3/80
2*3=6 5*4=20 answer is 6/20
3/5 * 1/4 = 3/20
3/5 * 1/4 = 3/20
3/20 (or 0.15) is.
1 and 7 over 20
as a fraction
63/4 * 3/5 = 27/4 * 3/5 = 81/20 = 41/20
20/6 = 10/3 or 3 and 1/3
5 times 4 is 20. then 20 times 3 is 60
19/20 x 5 = 95/20 or 4 and 15/20 or 4 and 3/4 19/20 = 0.95 x 5 = 4.75
5/21 * 7/20 = 5/3 * 1/20 = 1/3 * 1/4 = 1/12
