4 over 3
Divide by a fraciton mean multiplying by its reciprocal. (6/5) ÷ (9/10) = (6/5) × (10/9). Now, cancel BEFORE you multiply. Cancel a factor of 5 and factor of 3. (6/5) × (10/9) = (6/1) × (2/9) = (2/1) × (2/3) = 4/3. Leave the answer as an improper fraction: no need to change to a mixed numeral.
