Question 18858: Hello:
This is my first time here, and I am new to this. I am trying to prepare for a college entrance exam. (the math portion consists of pre-algebra and algebra.) Being that I Flunked out of both courses in high school, I am scared to death. This all seems so simple, yet I just do not comprehend. I am working with my husband who is an accountant and we have been able to figure out a few of the problems. But this is one we cant. I do not remember how to multiply or divide fractions. Thank you for ANY help on this.
Problem:
1/2 + (2/3 divided 3/4)-(4/5 x 5/6) = ?

You can put this solution on YOUR website!
+%281%2F2%29+%2B+%28%282%2F3%29%2F%283%2F4%29%29-+%284%2F5%29%2A%285%2F6%29+
Is that your question?
If it is,then we get:
+%281%2F2%29+%2B+%28%282%2F3%29%2F%283%2F4%29%29-+%284%2F5%29%2A%285%2F6%29+
To divide something by a fraction,turn the divisor upside down
+%281%2F2%29+%2B+%28%282%2F3%29%2A%284%2F3%29%29-+%284%2F5%29%2A%285%2F6%29+
Now we get
+%281%2F2%29+%2B+%288%2F9%29-+%284%2F5%29%2A%285%2F6%29+
Now cancel out the 5 we get
+%281%2F2%29+%2B+%288%2F9%29-+%284%2F6%29+
Simplifying 4/6 we get 2/3
+%281%2F2%29+%2B+%288%2F9%29-+%282%2F3%29+
Now taking the LCM
+%289+%2B+8%282%29+-+2%286%29%29%2F18+
+%289+%2B+16+-+12%29%2F18+
+%289+%2B+4%29%2F18+
+13%2F18+
Thats your answer.


Hope this helps,
