Hello.
Before we do anything, let's convert our 6 1/4 feet into inches (just to make things easier). We know that there are 12 inches in 1 foot, so 1/4 of a foot must be 3 inches (divide 12 by the denominator to find the value). Now we can multiply our 6 feet by 12 inches to get a product of 72 inches, and since we've found both values of 1/4 ft and 6 ft, we can sum up our products.
3 + 72 = 75; There are 75 inches in 6 1/4 ft.
Now, let's take a look at the problem and substitute 6 1/4 ft with 75 inches;
"Fernando is 75 inches tall. If one inch equals 2.54 centimeters, what is Fernando's height in centimeters?" This is much easier to understand, yes?
Let's now make an expression and simplify it with this information.
We have 75 inches. If each inch is equivalent to 2.54 centimeters, we need to multiply 75 by 2.54 in order to convert 75 inches to centimeters.
75 x 2.54 = 190.5
Fernando's height in centimeters is: 190.5 centimeters.
I hope this helps!
