It takes eight days to vaccinate 456 children, where the same number of children are vaccinated each day. How many children can be vaccinated in one day?

It took eight days to vaccinate 456 children. And we want to know how many children can be vaccinated in one day. We know that the same number of children are vaccinated each day. Because of that, we can use division to solve this problem. If we divide the 456 children by the eight days, it will tell us how many children can be vaccinated in one day.

We start by asking how many times can eight be divided into 45. Eight goes into 45 five times. Five times eight equals 40. After that, we need to subtract: 45 minus 40 equals five. Bring down the next digit; bring down the six; ask how many times does eight go into 56? Eight goes into 56 seven times, because seven times eight equals 56. 56 minus 56 equals zero, and there is no remainder. Each day, 57 children were vaccinated. And that means 57 children can be vaccinated in one day.
