They are equal
Step-by-step explanation:
Given

Required
Determine if they are equal
We start by equating both:

Cross Multiply


<em>Because both sides of the equation are equal, then the ratios are equal</em>
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.
For this one you can use 3/8 + 3/8 since 3+3 is equals to 6 and the 8 stays as it is.
I hope this helps.
