Question

The cost of 2 dozen banana is 3 3 by 7. find the cost of 1 banana. 3 3 by 7 is a mixed number.please answer me. the answer is 1 by 7. can you explain me how? please.

Answer 1

Step-by-step explanation:

=>1 dozen =12 bananas

=>2 dozen=(12×2)=24 bananas

$cost \: of \: 24 \: bananas \: = \frac{24}{7}$

$cost \: of \: 1 \: banana = \frac{24}{7} \div 24$

$cost \: of \: 1 \: banana = \frac{24}{7} \times \frac{1}{24}$

Both the 24 will be cancelled and we get

$cost \: of \: 1 \: banana = \frac{1}{7}$

Hope that it is helpfull.
