By taking a look at 1.64, you can already tell the 1 will be the whole number in the fraction. So let's focus on .64.
0.64 is in the hundredths place value, so the denominator will be 100. The unsimplified fraction would be 1 64/100.
To put this in simplest form we must divide 64 and 100. Let's start off with 2.
64/2 = 32
100/2 = 50
Let's continue until we can not divide by 2 anymore.
32/2=16
50/2 = 25
We can no longer divide by 2, howver there is not other number we can divide by both 16 and 25 evenly.
The answer in simplest form is 1 16/25
Part A: Determine the test average for your math class after completing test 2. (2 points)
Part B: Determine the test average for your science class after the completing test 2. (2 points)
Part C: Which class had a higher average after completing test 4? Show work to support your answer. (6 points)
We need to find a common denominator(bottom number of fraction)
5/3 = 25/15 (multiply both top and bottom by 5)
1/5 = 3/15 (multiply both top and bottom by 3)
Now since the denominator is the same we can add to get 25/15 + 3/15 = 28/15
