Question
What is to be added to $74.5$ to get $91$?
✓
Answer
In order to get the required number, we have to subtract $74.5$ from $91$
Required number$ = 91 - 74.5 = 91.0 - 74.5 = 16.5$
Working: $\ \ \ \ {91.0}\\\ \underline{-74.5}\\ \underline{\ \ \ \ 16.5}$
Required number$ = 91 - 74.5 = 91.0 - 74.5 = 16.5$
Working: $\ \ \ \ {91.0}\\\ \underline{-74.5}\\ \underline{\ \ \ \ 16.5}$
