Answer:
3
Step-by-step explanation:
it means that
16:3=57
16x:3x=57
16x+3x=57
19x=57
x=57/19
x=3
Step-by-step explanation:
Ratio = 16 : 3
Total people = 57
Total ratio = 16 + 3 = 19
people that are not recoverd = ̶5̶7 = 3
̶1̶9
= 3×16 = 48
people that recovered = 3×3 = 9
proof = 48 + 9 =57
so, the first answer is a ❌ wrong answer
RIGHT✔️ ANSWER IS 48
