Question

Myron is cooking meat. The double number line shows that he needs 12 hours to cook 5 kilograms of meat.

How long does Myron need to cook 3 kilograms of meat?

Answer 1

12/5 = x/3. Cross multiply

12*3=5x

36=5x divide both sides by 5.

7 1/5 hours

Answer 2

Answer:

Myron would need 7.2 hours to cook 3 kilograms of meat.

Step-by-step explanation:

We have,

Myron takes 12 hours to cook 5 kilograms of meat.

i.e. For 5 kilograms of meat, he takes 12 hours to cook.

Thus, for 3 kilograms of meat, he will need $\frac{12}{5}\times 3$ i.e. $\frac{12\times 3}{5}$ i.e. $\frac{36}{5}$ i.e. 7.2 hours

Hence, we get that,

Myron would need 7.2 hours to cook 3 kilograms of meat.
