Eight eights
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.
It would be 13/8 or 1 and 5/8
Three fourths plus one eight is 1 whole
1.135 :)
It is: 7/8+1/4+3/16 = 21/16
5/8
four and seven eights
Seven eighths 7/8
2 1/36
three fourths
seven
