When finding the mean you add up the numbers that are needed to find the mean and divide them by the amount of numbers you added. For example question 5 you will add 58+58+62+55+49+48 which will equal 330 and then divide it by 6 because there are 6 numbers which is 55.
Convert 8m to cm.
1 m = 100 cm
Multiply:
8 * 100 = 800
So 8 m is equal to 800 cm.
Both of them are equal, so 800 cm is not bigger than 8 m.
