Question

There are 2.54 centimeters in 1 inch. How many centimeters are there in 1 foot? In 1 yard? Explain your reasoning.

Answer 1

So if there are 2.54 cm in an inch that means that 1cm times 2.54=1 inch

there are 12 inches in a foot and 1 inch=2.54 centimter so
12 times 1 inch or 12 times 2.54=30.48 centimeters

there are 3 feet in a yard so we take the previous measurements and multiply

30.48cm in a foot times 3 feet in a yard or 30.48 times 3=91.44 cm in a yard

   if you want to do it the long way, you can multiply 2.54 with 12 with 3 and get      the same answer 91.44 cm in a yard
