Tim measures the length of four grasshoppers in his backyard: 5/4cm, 7/4cm, 9/4cm, 3/4cm. What is the average length?

1.5 cm

Step-by-step explanation:

To find averages, you add up all the values then divide by the amount of number there are (i.e, 6, 7, 8, so there would be three numbers and therefore divide by 3)

Step-by-step explanation:

In order to calculate the average, you need to add up all the numbers and divide them by the amount of numbers there are, so

5/4 + 7/4 + 9/4 + 3/4 = 24/4

24/4 divided by 4

is,

3/2, so the average is 1.5 simplified!

x/3-10=8

x/3=18

x=48
