There are 342 boys and 200 girls in
a school. How many more boys than girls are
there in the school?
In this question, we have to find
the difference between the number of boys and girls in a school. To find the difference, we could
subtract the number of girls from the number of boys. We could subtract 200 from 342. The number 342 has three 100s, four
10s, and two ones. To subtract 200, all we need to do
is take away two of our 100s counters. Now we have 100 left, and our tens
and ones digits haven’t changed. Three 100s take away two 100s
leaves us with 100. 342 subtract 200 equals 142.
If there are 342 boys and 200 girls
in a school, then there are 142 more boys than girls. We calculated the answer using our
knowledge of place value.
