1/4 divided by 6
1/4 * 1/6 = 1/24 (flip the second fraction if dividing)
15.
17/12 - 13/10
Make the denominator the same
17/12*5/5 - 13/10*6/6 = 85/60 - 78/60 = 7/60
16.
3/5 - 3/10 = 6/10 - 3/10 = 3/10
17.
Make the mixed number into an improper fraction
63/6 + 11/2 = 11/2*3/3 +63/6 = 33/6+63/6=96/6 = 12
18.
35/9, which is approximately 3.89, and it is between 3 and 4, but closer to 4.
19.
5/4*3/2=15/8
20.
Less. 46/40 is less than 46/5.
21.
12/5*7/4=84/20= 4.2 inches
22.
1/3 * 1/8= 1/24
1/24 * 8 = 1/3
23.
1/2 * 1/3 = 1/6
1/6 * 3 = 1/2
24.
4*7=28
I hope I am correct. Good luck.
