Answer:
2.4 hours
Explanation:
To find the number of hours it takes to cook 3 kilograms of meat, we must fist find the rate of the ration we have:
12 : 5
= 12 / 5
= 2.4
This means that if you mulitply this by the value of the weight of meat, you'll get the amount of time it takes to cook that amount of meat. We can do ths is find the time it takes to find the hours it takes to make 3 ilograms of meat:
x : 3
x = 3 * 2.4 = 7.2
x : 3
= 7.2 : 3
I takes 7.2 hours to cook 3 kilograms of meat. You can use this process to find all the other hours based on the weight.
I hope this helps! Tell me if I am wrong!
