Sagot :

Answer:

1. 3:1:4=112

3n+1n+4n=112

8n=112

n=14

juan=3(14)=42

mario=1(14)=14

jose=4(14)=56

Juan's weight os 42 kilograms

jose56-mario14=42

Jose is 42kilograms heavier than Mario

2. The ratio of the animals is 4:2:3:1.

Total of the ratio = 4+2+3+1=10

80/10=8

Cows=8×4=32

Carabaos=8×2=16

Goats=8×3=24

Horses=8×1=8

32:16:24:8.

Add all four and you get 80!

3. There are 12 apples & 16 bananas, the total of fruits are 46.
