Question

An inch contains \[2.54\] cm. How many centimeters will there be in \[12.5\] inches?

Answer 1

Hint: Here, we will use the given condition as our conversion factor from inches to centimeters and then multiply the \[2.54\] cm by \[12.5\] inches to find the value in centimeters.

Complete step-by-step answer:
We are given that an inch contains \[2.54\] cm, that is, \[1{\text{ inch}} = 2.54{\text{ cm}}\].
Now we have to compute the centimeters for \[12.5\] inches by multiplying it by \[2.54\] cm using the given condition.
\[ \Rightarrow 12.5 \times 2.54 = 31.75{\text{ cm}}\]
Thus, we have that \[12.5{\text{ inches}} = 31.75{\text{ cm}}\].
Hence, there will be \[31.75\] centimeters in \[12.5\] inches.

Note: In solving these types of questions, students should know the basics about inches and centimeters. We have to use the given condition as our conversion factor from inches to centimeters. Some students divide the value \[12.5\] by \[2.54\] instead of multiplying them, which is wrong. This question is simple, but take care of calculations.
