Question

What is the part-to-part average of 79-70?Give your answer using a colon.

Answer 1

6th-Grade average=100-90,89-80,79-70
Total of students=32,65,and 27
What is the part-to-whole ratio for the 6th-Grade average of 79-70?

Answer 2

The part-to-part average of two numbers is calculated by finding the ratio of the two parts. In this case, you have the numbers 79 and 70.

To express this using a colon, place the two numbers in the form of a ratio:

79 : 70

This is the part-to-part average expressed as a ratio.

Answer 3

To find the part-to-whole ratio for the 6th-grade average of 79-70, you need to use the number of students in that range compared to the total number of students.

1. **Number of students in the range 79-70**: 27
2. **Total number of students**: 32 + 65 + 27 = 124

Now, the part-to-whole ratio can be calculated as follows:

\[
\text{Part-to-Whole Ratio} = \text{Number of students in 79-70} : \text{Total number of students} = 27 : 124
\]

So, the part-to-whole ratio for the 6th-grade average of 79-70 is **27:124**.
