3.for which value of m is 4/16=m/24 a proportion?

A. m=6
B. m=8
C. m=12
D. m=14

1. Damon

(7/9)(4/4) = 28/36
14/18 (3/2 / 3/2) = 21/27

The easy way is to use your calculator, for example 14/18 = .777777..... and 21/27 =.77777.....
but
30/80 = .375 and 8/18 = .4444...

2.
3*6 = 24 but 5*6 = 30 not 40
30/2 = 15 but 10/5 = 5 not 3
14/3 no way
but
7*2 = 14 and 12*2 = 24 YES

3.
16 m = 4*24
m = 6

check
4/16 = 1/4
6/24 = 1/4 yes
