Answer:
Step-by-step explanation:
Ok so first you would have to distribute the first side (left of the equal sign) So you would get 5+10m. Then do the next side 1/2 times 8 equals 4 and 1/2 times 20 m. Which is 10m. So 4+10m and 5+10m there for it would be false. They do not equal the same.
Proprtional is
x/y=k where k is a constant
compare
1 and 0.33
2 and 0.66
0.33/1=0.33
0.66/2=0.33
same
it is proportional
