Answer:
the ratio used was 1:19
Explanation:
let a be the action figure version
let r be the real iron man
let's list out the important things.
a = 4''
r = 6'4''
one foot has 12 inches
convert r into inches:
6 × 12 = 72 (6 feet in r)
r = 76'' (72 + 4)
r = 76''
a = 4''
ratio is 4:76
simplify
4:76
2:38
1:19
the ratio they used is 1:19
good luck,
