12/8 or 1 and 1/2
Seven eights plus three eights is ten eights. Now, possibly you intended to ask about eighths, rather than eights. Ten eighths is equal to one and a quarter. However, ten eights is equal to 80. The extra h makes a difference.
Yes.Note that I changed the spelling of the question.three fourths is NOT equal to six eights but it is equal to six eighths. that pesky h makes all the difference!Six eights is 6*8=48
Yes
what does seven plus equal
Three quarters is the simplest form for six eights. For five eights there is no simpler form.
