3/3 x 1/5 = 3/15
3/3 = 1/1 = 1
Answer: 1
1/5 = 3/15
15 choose 3 = 15!/(3!*(15-3)!) = 15!/(3!*12!) = (15*14*13)/(3*2) = 5*7*13 = 455
There are 15 because 15/5 = 3
183. 15*12 +3 =183
1, 3, 5, 15
15 of them because 15/5 = 3
3*5=15 5*3=15 15*1=15
15
15, 3 multiplied by 15 equals 4545 ÷ 3 = 15
15 of them because 15/5 = 3
3/15
There are 5 thirds in 15 because 15/3 = 5, so 5 x 3 = 15.
75/15 = 15/3 = 5
15
15 ÷ 5 = 3.
15/5 = 315/5 = 3
50 divided by 15 = 3 times (45) with 5 remaining
9/3*5=15
