Hi im new to this, Im in 7th grade and im failing math i need help with this question:

Question

On a recent survey, 60% of those surveyed indicated that they preferred walking to running.

a. If 540 people preferred walking, how many people were surveyed?

b. How many people preferred running?

Answer 1

So 540 represents 60% or .60 of the total
so the total is 540/.60 = 900

So if 540 prefer walking, then 900-540 or 360 prefer running

check:
take 60% of 900
= .60*900 = 540, I am right!
