# Explanation:## Step1: The question provides a ratio but does not present it in mathematical form. Given the example, let
represent the total number of passengers and let
be the number of children. We know that
based on the question. Up to this stage, the ratio of children to total passengers has been established.## Step2: From the problem, the pie chart likely provides us with the percentage for adults or the equivalent fraction so that we can write a proportion to solve for
. Let assume the percentage of adults
in flight if 70%. Write the partial proportion \( c/96 = (100 - A) / 100 \). Which is equivalent to
## Step3:Solve for
by using an algebraic operation; multiply the cross members to perform the equivalence. ### Let’s plug our pristine values into the proportion: ###
## Step4:Calculate the values of result, which is \( n = ((100 * 96) / 100)\)## Step5: Adjust the proportion to find the number of adults correspondingly regulating the proportion
.### Put existing values into proportion, compute \( Adults = ((A * n) / 100) \)## Step6: Execute computation to get the answer.# Answer: As a result of the calculation,adian number to My Working Steps:# Conclusion:## Step 1: Note: There aren't specific numbers stated in the problem so an example with arbitrary numbers has been created.## Step 2:Given: The plane has 96 children and the Pie chart indicates that the proportion of children to the total passengers on the plane is, say, 60% (in absence of specific information in the problem). If we formulate this information, it forms the ratio:
. Let's symbolize the total number of passengers (children and adults put together) as 'n'. ## Step 3Cross-multiplication yields:
. ## Step 4:Calculation according to the formula yields:
160 people are flying on this plane in total.## Step 5:For estimating the number of adults, subtract the number of children (which is 96), from the total:
. This implies the number of adults on the plane.# Answer:If the percentage of children on the plane is 60%, then the total number of adults on the plane would be 64 adultsacific]: number['''Number of adults, computed}'.
