Answer 1

816

Explanation:

Find total number of people asked by adding all the people.

54 + 56 + 52 + 63 = 225

So, 54 out of 225 people have their favorite snack as brownies.

We need to find out how many it is for 3,400. We can do that by cross multiplying.

54 = x (did it like this so it's better visually)

225 3400

Multiply both sides by 3,400 and divide to get:

x = 816
