K12? Me too.
It would be educated guess. I just finished that practice cause I'm catching up :) Good luck!
The average is 105.5. To find the average, you have to add up all numbers, 63+148=211. Now you have to divide by how many numbers there are, 211÷2=105.5
Looks like A is the answer.
<h3>5/6 × 3/10</h3>
<em>Multiply 5/6 by 3/10 (to do this,</em><em> multiply the numerator by the numerator </em><em>and the </em><em>denominator by the denominator).</em>
<h3>5 × 3/6 × 10</h3>
<em>Perform the</em><em> multiplications </em><em>in the </em><em>previous fraction.</em>
<h3>15/60</h3>
<em>Reduce the fraction </em><em>15/60</em><em> to its</em><em> lowest expression by extracting</em><em> and canceling 15.</em>
<h3>1/4 ≈ 0.25</h3>
