Difference means to minus
5 1/4 - 2 3/4 =
[since 1/4 cannot minus 3/4, we need to convert one of the 5 wholes into quarters: 5 1/4 = 4 5/4 ]
5 1/4 - 2 3/4
= 4 5/4 - 2 3/4
= 2 2/4
= 2 1/2

<em>4xy¹¹/x⁷y⁶ × 6x⁸y/8x³ = 3y⁶/x</em>
<em>12)</em>
<em>y¹⁰/2x³ × 20x¹⁴/xy⁶ = 10x¹⁰y⁴</em>

<em>(5xy/8x⁻¹y²)² × 26y³/5x²y⁵ =</em>
<em>= 25x⁴/64y² × 26/5x²y²</em>
