$8 1/4$

Explanation:

First method

$3xx2=6$

$3xx3/4=9/4$

$9/4=2 1/4$

Answer

$6+2 1/4=8 1/4$

Second method

$2 3/4= 2/1 + 3/4 = 8/4 + 3/4 =11/4$

$3xx11/4=33/4$

Answer 2 · 2018-03-26T19:22:54

$8 1/4$ pounds of flour.

Explanation:

If you do $2$ (the whole number) times $3 = 6$ .

Leave that for now, make the $3/4$ in a percentage:

$3/4 * 100% = 75%$

Multiply this by $3$ and you get $225%$ . Make this percentage into a fraction:

$(225%)/(100%) = 2.25= 2 1/4$

Add the two values together:

$6+ 2 1/4 = 8 1/4$

Hope this helps!
