Question

In a certain office the ratio of women to men is 2:9. how many men would you expect to find in a group of 132 people

Answer 1

we have a ratio of 3:2. we have to add them so we have 5, now we multiply 2 (ratio of cats) by 20 (the total number), which gives us 40, finally we divide 40 by 5 (3+2)= 8. similarly, we can multiply 3 (ratio of dogs) by 20 and then divide by 5= 12.
