a math exam is marked out of 120. draw a conversion graph to change the following marks to percentages.
a_80 b_110 c_54 d_72
percentage=score/120 x 100
To draw a conversion graph to change the given marks to percentages, follow these steps:
Step 1: Determine the maximum possible score on the exam
The math exam is marked out of 120, which means the highest possible score one can achieve is 120 marks.
Step 2: Convert each mark to a percentage value
To convert each mark to a percentage, use the formula:
Percentage = (Mark / Maximum Mark) * 100
For the given marks, we can calculate the corresponding percentages as follows:
a) For mark 80:
Percentage = (80 / 120) * 100 = 66.67%
b) For mark 110:
Percentage = (110 / 120) * 100 = 91.67%
c) For mark 54:
Percentage = (54 / 120) * 100 = 45%
d) For mark 72:
Percentage = (72 / 120) * 100 = 60%
Step 3: Draw the conversion graph
On the y-axis, label the marks from 0 to 120, and on the x-axis, label the percentages from 0% to 100%. Use these markings to plot the following points:
a) (80, 66.67)
b) (110, 91.67)
c) (54, 45)
d) (72, 60)
Connect the points with straight lines to form a graph. You can label each point with the corresponding letter (a, b, c, d) to facilitate understanding.
