+164 Ralph walks 1 1/4 miles home from school every day. He stops at Joe's house, which is 5/6 of a mile from school. How far is it from Joe's house to Ralph's house?
+313 ∴ Joe's house is ( \(1{1 \over 4}\)-\( {5\over 6}\)) mile far
from Ralph's house
i.e (\(1{1 \over 4}\)-\( {5\over 6}\)) = ( \({4 + 1\over 4}\)-\( {5\over 6}\))
= ( \({5\over 4}\)-\( {5\over 6}\))
= ( \({5 * 3 - 5 * 2\over 12}\))
= \({15 - 10\over 12}=\)-\( {5\over 12}\)
∴ Joe's house is \(({5 \over 12})\) mile far from
Ralph's house
