To add <math xmlns=”http://www.w3.org/1998/Math/MathML”><semantics><mrow><mfrac><mn>1</mn><mn>4</mn></mfrac></mrow><annotation encoding=”application/x-tex”>\frac{1}{4}</annotation></semantics>[/itex]41​, <math xmlns=”http://www.w3.org/1998/Math/MathML”><semantics><mrow><mn>2</mn></mrow><annotation encoding=”application/x-tex”>2</annotation></semantics>[/itex]2, and <math xmlns=”http://www.w3.org/1998/Math/MathML”><semantics><mrow><mn>1</mn><mfrac><mn>1</mn><mn>2</mn></mfrac></mrow><annotation encoding=”application/x-tex”>1 \frac{1}{2}</annotation></semantics>[/itex]121​, follow these steps:

1. Convert mixed numbers to improper fractions:

• <math xmlns=”http://www.w3.org/1998/Math/MathML”><semantics><mrow><mn>1</mn><mfrac><mn>1</mn><mn>2</mn></mfrac><mo>=</mo><mfrac><mn>3</mn><mn>2</mn></mfrac></mrow><annotation encoding=”application/x-tex”>1 \frac{1}{2} = \frac{3}{2}</annotation></semantics>[/itex]121​=23​
2. Find a common denominator for the fractions:

• The denominators are 4 and 2. The least common denominator is 4.
3. Convert <math xmlns=”http://www.w3.org/1998/Math/MathML”><semantics><mrow><mfrac><mn>3</mn><mn>2</mn></mfrac></mrow><annotation encoding=”application/x-tex”>\frac{3}{2}</annotation></semantics>[/itex]23​ to have a denominator of 4:

• <math xmlns=”http://www.w3.org/1998/Math/MathML”><semantics><mrow><mfrac><mn>3</mn><mn>2</mn></mfrac><mo>=</mo><mfrac><mrow><mn>3</mn><mo>×</mo><mn>2</mn></mrow><mrow><mn>2</mn><mo>×</mo><mn>2</mn></mrow></mfrac><mo>=</mo><mfrac><mn>6</mn><mn>4</mn></mfrac></mrow><annotation encoding=”application/x-tex”>\frac{3}{2} = \frac{3 \times 2}{2 \times 2} = \frac{6}{4}</annotation></semantics>[/itex]23​=2×23×2​=46​
