Question 930170
Let's put this into the area formula. The formula for the area of a triangle is {{{A=lw}}}. A is area, l is length, and w is width. We already know the area, {{{1/2}}}, and the length, {{{3/8}}}, so let's plug that in.

{{{1/2=(3/8)*w}}}

Now divide {{{3/8}}} from both sides. Divide {{{1/2}}} by {{{3/8}}}. When we divide fractions, you flip the fraction you are dividing by and multiply it to the original fraction. So we multiply {{{1/2}}} by {{{8/3}}}.

{{{1/2*8/3=8/6}}}

Simplify {{{8/6}}}.
{{{4/3}}}

Now we know that {{{w=4/3}}}, so the width is 4/3 inches. Hope I helped! :)
