Common factors are the numbers that both numbers in the pair can be divided by equally (no decimals)
e.g. 32 and 40 - Common factors of 2 and 4 (32/2=16, 40/2=20, 32/4=8, 40/4=10)
Answer: 186
<u>Step-by-step explanation:</u>
<u> Jazz </u> <u>Rock or Pop </u>
7-12: 200 - 142 = 58 142
13-18: 72 - 58 = 14 200 - 14 = 186
It is given that 142 out of 200 students in age group 7-12 like Rock or Pop.
Therefore, 200-142 = 58 in that age group like Jazz.
Total Jazz in both age groups is 72, so 72 - 58 (7-12: Jazz) = 14 students in age group 13-18 like Jazz.
There are 400 students total and 200 are in age group 7-12, which leaves 400-200 students in age group 13-18. 200 - 14 (13-18: Jazz) = 186 students in age group 13-18 like Rock or Pop.
