To find 7/8 of an inch on a ruler, begin with the very first line and count 14 lines. The 14th line demarcates 7/8 of an inch.
Continue ReadingRulers are divided into inches, and inches are divided into sixteenths. In order to find 7/8 of an inch, it is necessary to determine the value of 7/8 in regard to 16. Since eight goes into 16 two times, it is only necessary to multiply both the top and bottom numbers of the fraction by two in order to find the answer, which is 14/16. The 1/8-inch marks on a ruler are slightly longer than the smallest lines, which indicate 1/16. So 7/8 of an inch can be found faster by simply counting seven of the 1/8-inch demarcations.
