QuestionConvert Peter's 15/20, Khando's 7/10, and Mellisa's 17/25 to percentages to find who scored the highest.

Studdy Solution

STEP 1

Assumptions1. Peter's score is15 out of20. Khando's score is $\frac{7}{10}$
3. Mellisa's score is17 out of254. We need to convert all scores to percentages to compare them

STEP 2

First, let's convert Peter's score to a percentage. We can do this by dividing his score by the total possible score and then multiplying by100.
$Peter's\, percentage = \frac{Peter's\, score}{Total\, possible\, score} \\times100$

STEP 3

Now, plug in the given values for Peter's score and the total possible score to calculate his percentage.
$Peter's\, percentage = \frac{15}{20} \\times100$

STEP 4

Calculate Peter's percentage.
$Peter's\, percentage = \frac{15}{20} \\times100 =75\%$

STEP 5

Next, let's convert Khando's score to a percentage. We can do this by multiplying her score by100, since her score is already given as a fraction of1.
$Khando's\, percentage = Khando's\, score \\times100$

STEP 6

Now, plug in the given value for Khando's score to calculate her percentage.
$Khando's\, percentage = \frac{}{10} \\times100$

STEP 7

Calculate Khando's percentage.
$Khando's\, percentage = \frac{7}{10} \\times100 =70\%$

STEP 8

Finally, let's convert Mellisa's score to a percentage. We can do this by dividing her score by the total possible score and then multiplying by100.
$Mellisa's\, percentage = \frac{Mellisa's\, score}{Total\, possible\, score} \\times100$

STEP 9

Now, plug in the given values for Mellisa's score and the total possible score to calculate her percentage.
$Mellisa's\, percentage = \frac{17}{25} \\times100$

STEP 10

Calculate Mellisa's percentage.
$Mellisa's\, percentage = \frac{17}{25} \\times100 =68\%$

STEP 11

Now that we have all the percentages, we can compare them to see who got the highest mark.Peter got75%, Khando got70%, and Mellisa got68%. Therefore, Peter got the highest mark.
