Question

Dale must choose a number between 61 and 107 that is a multiple of 2, 4, and 5 .

Answer 1

The number must be a multiple of 10 i.e end in 0 because it has t be a multiple of 5 but also 2, so it has to be even.
so that gives you options of: 70, 80, 90 and 100. 4 does not go into 70 or 90 but it does go into 80 and 100.
Dale could choose 80 or 100 as his number.

Hope this helps :)

Answer 2

80 is devisable by all
