Ok, it's really easy.... You simply need to know the English - metric equivalent for any conversion such as this. 1 inch is equal to 2.54 centimeters. So, you then need to convert all numbers to decimal fraction. 7 3/4 is of course 7.75. Then, you simply set up the conversion - mathematically. It looks like this:
7.75 inches x 2.54 cm / 1 inch = 19.685 cm
Now that you know the procedure, try a different conversion:
10 1/4 inches would translate to how many centimeters?
Answer: a. 25.5 b. 26.0 c. 28.2 d. 20.9 ?
The correct choice is B.
Hope this helps.
