Divide both parts by their highest common factor, which is 4. That gives you 4 over 7.
No.
Yes.
28/336 = 1/12
No.
no
a/7 + a/4 = 4a/28 + 7a/28 = 11a/28
To simplify 28 / 35, you divide by the GCF of 28 and 35. The GCF is 7, so 28 / 35 / 7 = 4 / 5.
No, you can't, believe
12/28 = 3/7 = 0.428571428
No, you can't.
1 over 2
25 over 16.
