1. ## Need help with fraction problem solving- help please

Cindy spent 1/8 of her money on candy and 1/4 of her money at the movies.
She had $25.00 left How much did she have to start with. Need help with daughters 4th grade math- please help Thanks, Neil Ps I need to show the work 2. I indeed messed up.. .. knew i was missing it somewhere. My apologize. 3. Originally Posted by ixo$\displaystyle \frac{\$25}{8} + \frac{\$25}{4} +\$25 =$ total amount
Ixo , you have done a bit of carelessness here,

$\displaystyle \frac{\$25}{8} + (\frac{\$25}{4}\cdot \frac{2}{2}) +(\$25\cdot \frac{8}{8} )= $total amount$\displaystyle \frac{25}{8} + \frac{50}{8} +\frac{200}{8} = $total amount$\displaystyle \frac{275}{8} = $total amount$\displaystyle \$34.375 =$ total amount

Which doesn't make sense because movies didn't cost that much back when they were using 1/10 th of a cent
Lets say Cindy has x$in the beginning Now the equation that we can form with this is$\displaystyle
x = \frac{x}{4}+\frac{x}{8} + 25

$Hence$\displaystyle
x= \frac{2x+x}{8} + 25
\displaystyle

x - \frac{3x}{8} = 25

\displaystyle \frac{5x}{8} = 25 $Hence$\displaystyle x= \frac{200}{5} = 40$Thus starting amount is 40$

Please show the work to your daughter and ask if she still has troubles
Best of Luck
