Hi,
Please see the picture I had to upload in order for this question to be complete. Please also note that Kara has 3 buttons in the 3/4 length. You have to sum up only those in that length and ignore the ones in different lengths.
It is a very simple multiplication, and there are 2 ways to do so. You can use either fractions or integer numbers. See the 2 options below:
3/4 (fractions) = .75 (integer numbers)
Option one - 3 * 3/4 = 9/4 which is represented by 2 and 1/4.
Option two - 3 * .75 = 2.25
Have a good one!
