Question

Belinda has a box of24 bananas. If \[\dfrac{1}{4}\] of them are ripe. How many ripe bananas does she have?

Answer 1

Hint: In the above given question we know the overall amount of bananas, we also know the ratio of how many bananas out of the lot are ripe which the question wants us to calculate, so to calculate this we are going to multiply the ratio with the whole lot which will give the number of ripe bananas out of the whole lot.

Complete step by step solution:
In the above question it is already stated that the overall amount of the substance that is the number of bananas is 24.
It is also mentioned that bananas that has been mentioned in the question are a mixture of ripe and unripe and in the question it is asked that the amount of banana that are ripe are equivalent to \[\dfrac{3}{8}\]of the overall amount of bananas that has been mentioned in the question as 24.
To find the number of bananas that are ripe out of 24 bananas as mentioned in the question we will multiple the ratio of ripe bananas to that of overall number of bananas and we get
\[=\left( 24 \right)\left( \dfrac{3}{8} \right)\]
On solving the above equation we get:
\[\Rightarrow \left( 24 \right)\left( \dfrac{3}{8} \right)=9\]
From the above statement we can say that \[\dfrac{3}{8}\] part of 24 is equal to 9, from which we can conclude that the number of bananas that are ripped out of the given 24 bananas is 9.

Note:
To solve this kind of problem, always try to find the amount or part of the substance that is required and then multiply it with the overall amount of that substance. As we have done in this question, we have multiplied the ratio that was mentioned for ripped and then multiplied it with the overall amount of the substance that was given to achieve the final answer.
