Question

If the ratio of tourists to locals is 3:7 and there are 60 tourists at the opening of a new museum, how many locals are in attendance?

Answer 1

140 locals in attendance

Explanation:

given the ratio tourists : locals = 3 : 7 and there are 60 tourists

the 3 part of the ratio refers to the 60 tourists.

divide 60 by 3 to find the value of one part of the ratio.

60 ÷ 3 = 20 ← value of 1 part of the ratio , then

7 parts = 7 × 20 = 140

There are 140 locals in attendance.
