- Simple Equations Involving Fractions
To solve simple equations containing fractions, first eliminate the fractions by multiplying each term in the equation by the LCM of the denominator.
Worked Example 9.1.1:
Solve the following:
i. \( \frac{x}{12} = \scriptsize 5 \)
ii. \( \frac{x}{9} = \frac{4}{3}\)
iii. \( \frac{y \: – \: 5}{4} = \scriptsize 8 \)
iv. \( \scriptsize 2x \: – \: \normalsize \frac{x}{8} = \scriptsize 12 \frac{1}{2} \)
v. \( \frac{5x \: – \: 1}{4} = \frac{2x \: – \: 1}{2}\)
Solution
i. \( \frac{x}{12} = \scriptsize 5 \)
\( \frac{x}{12}\scriptsize \: \times \: 12 = 5 \: \times \: 12\)
\( \scriptsize x = 12 \: \times \: 5 \\ \scriptsize = 60\)
