13 cans of paint with 5/6 liters of paint in each were used to paint 4 identical cars. How can you calculate the amount of paint

brilliants [131]

Answer:

(B) 5/6 ·13÷4

(D) 5/6 · 13/4

Step-by-step explanation:

Amount of paint per can = $\frac{5}{6}$ liters.

Number of cans used to paint 4 cars = 13

Total amount of paint used for 4 cars = $13 * \frac{5}{6}$ liters.

= $\frac{13 * 5}{6}$ liters.

= $\frac{65}{6}$ liters.

Total amount of paint used for 1 car = $\frac{65}{6} \div 4$ liters.

= $\frac{65}{24}$ liters.

Of the given options, option B,C and D correspond to the same value.
