Yes, because 8/15 = 24/45
6/45 + 20/ 45 = 26/45
4/9 = 20/45 8/15 = 24/45
45/60 = 15/20 = 3/4
No - 4/8 in its simplest form is 1/2. 20/45 in its simplest form is 4/15
If 20 = 100% then 45 = 225% So, 45 is an increase of 125% on 20
4/5 x 9/9 = 36/45 4/9 x 5/5 = 20/45 so 4/5 is greater
3/5 ÷ 4/15 3/5 * 15/4 45/20 9/4■
15 over 45 into decimal = 0.3333
10 + 15 + 20 = 45
No. 45 over 15 and 21 over seven are equivalent though.
20 = 5 + n/3 15 = n/3 n = 45
