Question

Write two multiples of 3 that have a factor of 7. Use equations to explain.

Answer 1

Equation:

y = 3 (7) x

For x = 1, y = 21... it is multiple of 3 and it has a factor of 7

for x = 2, y = 42...is it is multiple of 3 and it has a factor of 7

Answer: 21 and 42

Both can be divided by 3 and by 7

21/3 = 7

21/7 = 3

42/3 = 14

42/7 = 6
