Question 446090
"It takes Emmet 25 minutes to finish {{{2/3}}} of his homework."
x = number of minutes it takes Emmet to finish ALL of his homework
{{{(2/3)x}}} = number of minutes it takes for Emmet to finish {{{2/3}}} of his homework
{{{(2/3)x = 25}}}
Multiply both sides by 3: {{{2x = 3(25)}}}
{{{2x = 75}}}
Divide both sides by 2: {{{x = 75/2}}}
x = 37.5 or 37-1/2
Therefore, it will take 37-1/2 (or 37.5, whichever version--mixed number or decimal--you prefer) minutes for Emmet to finish all of his work.
