To find out the number of children on the bus, we can calculate 3/10 of the total number of passengers.
If there are 80 passengers in total, we can find the number of children by multiplying 80 by the fraction 3/10:
Number of children = 80 * (3/10)
To simplify the calculation, we can multiply the numerator first and then divide by the denominator:
Number of children = (80 * 3) / 10
= 240 / 10
= 24
Therefore, there are 24 children on the bus.
