Ok so first you write out the proportions
29.6 46,600
——— = —————
100 x
Then we cross multiply.
29.6x = 4,660,000
Then we multiply both sides by 10 to clear the decimal.
296x = 46,600,000
Then we dived each side by 296
x = 157,432.432432432432
Basically since you can’t have .432432432432 of a doctor, you would just write your answer as
157,432 doctors
Hope this helps!
