Answer:

26

Step-by-step explanation:

To find the average of a collection of values, add them all up and then divide the sum by the number of values.

25+36+20+15+24+30+38+18+32+22=260

The sum is 260, and there are 10 values here.

260\div10=26

The average score is 26.

Mateo makes 6 leaves of banana bread. he sells 2/3 of the loaves at bake sale. Which expression represents how many loaves Mateo
erica [24]
No expressions provided to choose from, to find 2/3 of 6 loaves, you need to multiply the percentage by the number of loaves.

2/3(6 loaves)
=2/3(6/1)
=12/3
=4

Understanding how to check answer:
6 divided by 3 (because this problem is dealing with thirds).
6÷3=2
2 + 2 + 2 = 6
Since they want to know what 2 of the 3 pieces is, add 2 + 2= 4.

Hope this helps!! :)
