Question

Which pair of numbers has twelve as a common factor?

forty-eight and sixty-six

sixty and eighty-four

3 and 4

thirty and seventy-two

Answer 1

this question is asking which pair of numbers can be divided evenly by 12

3 and 4 are too small, you will get a fraction

we can test 48 and 66: 48/12 = 4 that works, and 66/12= 5 remainder 6 Does NOT work

can you test 60 and 84
and 30 and 72 ?
