โš ๏ธ Common Mistakes & Teacher Fixes

โš ๏ธTrying to Find a Common Denominator

Why students stumble: Students carry over addition rules into multiplication, wasting time converting fractions to common denominators.

Teacher Fix: Remind students that multiplication does NOT require common denominators. Simply multiply top ร— top and bottom ร— bottom.
Example: For 2/3 ร— 3/5, do not convert to /15 before operating. Multiply: (2 ร— 3)/(3 ร— 5) = 6/15 = 2/5.
โš ๏ธForgetting to Cross-Cancel Before Multiplying

Why students stumble: Multiplying large numbers (e.g. 7/12 ร— 4/21) leads to unwieldy products like 28/252, where finding common factors is error-prone.

Teacher Fix: Cross-cancel 7 with 21 (divide both by 7 to get 1 and 3) and 4 with 12 (divide both by 4 to get 1 and 3): (1 ร— 1)/(3 ร— 3) = 1/9.
Example: 7/12 ร— 4/21 = (1 ร— 1)/(3 ร— 3) = 1/9.
