MTH1W.B3.4
Grade 9 de-streamed — Solve problems involving operations with positive and negative fractions and mixed numbers, including in linear relations.
A note on this mapping: Ontario has no expectation for "clear the denominators with the LCD"; B3.4 is the nearest, framed as fraction operations rather than as an equation-solving technique, so this pairing is a judgement call.
The skill that covers it
What a student should be able to do
- Multiply both sides by the least common denominator to clear fractions.
- Solve equations with fractional coefficients and constants.
- Solve simple proportions as rational equations.
- Check solutions and exclude values that make a denominator zero.
