Express 3 - frac x - y y as a single fraction - WAEC Mathematics 2012 Question
Express 3 - [\(\frac{x - y}{y}\)] as a single fraction
A
\(\frac{3xy}{y}\)
B
\(\frac{x - 4y}{y}\)
C
\(\frac{4y - x}{y}\)
D
3 - \(\frac{x - y}{y}\)
correct option: c
(\(\frac{x -y}{y}\)); \(\frac{3}{1} - \frac{x y}{y}\)
= \(\frac{3y - (x - y)}{y}\)
= \(\frac{3y - x + y}{y}\)
= \(\frac{4y - x}{y}\)
= \(\frac{3y - (x - y)}{y}\)
= \(\frac{3y - x + y}{y}\)
= \(\frac{4y - x}{y}\)
