A farmer has 377 hens and 293
ducks. How many birds does he have
altogether?
This is a word problem. Usually, when we see the word
“altogether,” this means we need to add. So we’re being asked to find the
total number of birds. We know the farmer has 377 hens,
and we also know he has 293 ducks. When sketching a bar model in this
way, we can see what we need to do next. To find the total number of birds,
we need to add together 377 and 293. We could add using the standard
written method.
Let’s start by adding the ones. Seven ones and three ones gives us
a total of 10 ones. We can write our zero in the ones
place, and we need to carry the 10 into the tens column. Seven 10s plus nine 10s gives us 16
10s, plus the one we carried gives us 17. We can write the seven in the tens
column and the one in the hundreds column.
Now we just need to add the
hundreds. Three plus two plus one gives us a
total of six 100s. 377 plus 293 is 670. If a farmer has 377 hens and 293
ducks, then he has 670 birds altogether.
