(to nearest 1/5 inch) (to nearest centimeter)
6 7/8 21 3/5 55
? ? 62
The first is rounded to the nearest eith inch and second is rounded to neares fith inch.
----------------
x/(6 7/8) = 62/55
---
x/(55/8) = 62/55
8x/55 = 62/55
8x = 62
x = 31/4 = 7 3/4
-----------------------------
x/(21 3/5) = 62/55
x/(108/5) = 62/55
5x/108 = 62/55
5x = 108(62/55)
x = 24.3491
