**Question: 2 1/7 + 1 1/4. Step 1: **Rewrite the calculation to simplify (Combine integers) = 2+1+(1/7)+(1/4)=3+(1/7)+(1/4) **Step 2: **Find the lowest common factor of 4 and 74 8 12 16 20 24. **28** 7 14 21 **28** **Step 3: **Rewrite the fractions(1/7)+(1/4) = (1x4)/(4x7) +(1x7)/(4x7) = (4/28)+(7/28) = 11/28 **Step 4: **Combine and Simplify 2 1/7 + 1 1/4 = 3 + 11/28 = (3x28 + 11)/28 = 95/28 **Step 5: **Think if the answer is what you'd expect / Validate with another method
