LCM(8, 5, 15) = 120 so the answer is 120 and all its multiples.
120 (which can be found by multiplying 15 and 8)
[15 - (5 + 6)]*2 = [15 - 11]*2 = 4*2 = 8
15 R 5
5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.
Neither. 8 and 5 is 13.
8, 5 and 3 can all go into 120 evenly.
1/5 - 8/15= 1x3/5x3 - 8/15= 3/15 - 8/15= (3 - 8)/15= -5/15= -5÷5/15÷5= -1/3
-3*6x+5/8=6x-1 * (-3*(6x+5))/8?If this is your question, then:LHS = -3 * 6x + 5/8 = -18x + 5/8RHS = 6x - 1 * (-18x-15)/8 = 6x + (18x+15)/8 = 48x/8 + 18x/8 + 15/8 = 66x/8 + 15/8-18x + 5/8 = 66x/8 + 15/866x/8 + 18x = 15/8 - 5/8210x/8 = 10/8210x = 10x = 10/210 = 1/21
4/5 - 8/15 = 12/15 - 8/15 = 4/15
for example if you have 2:5:8 all you do is add them together and divide it by how many numbers theyr are so 2+5+8=15 15/3=5 so the answer is 5.
To calculate the hours from 8:45 to 5:15, first determine the time from 8:45 to 9:00, which is 15 minutes. Then, from 9:00 to 5:00 is 8 hours, and from 5:00 to 5:15 is an additional 15 minutes. Adding it all together, the total time is 8 hours and 30 minutes.
(8/15) / (5/3) = (8/15) x (3/5) = (24/75) = 8/25
