Can you help me with fractions?

Actual Question: 3/4 of a whole cake was eaten on Sunday. If two pieces are eaten on Monday and there are three pieces left, how many pieces of cake were there to start?

Well, 1/4 of the cake was left on Sunday. Then what was eaten on Monday plus what was left on Monday tells you how many pieces were in 1/4 of the cake.

When you are trying to do this type of problem, it's less about the math that looking at what you can correctly state about the problem from the facts you are given about the problem.

I'm pretty good at math, but it still took me a minute to dig out the information and figure out the relationships between the amounts.

I think there is a total of 20 pieces. On Monday there was a total of 5 pieces, 2 that were eaten and the 3 that was left, that is what make 1/4. Now multiply 5 times 4 to complete the whole.

A fraction is no more than a division problem, the numerator is above a horizontal line and the denominator is below the line, you always divide the denominator into the numerator. Another thing to remember is 1/1=1. or 43/43=1, or 125/125=1 and so on. Also remember in fractions the only thing you add or subtract is the numerator, in multiplication you multiply both the numerator and the denominator. Being a carpenter I learned to think of fractions terms of an inch, if look at a ruler the inch is divided into 16 parts, or 8 larger parts of 2 of the 16 parts, or 4 larger parts with 2 of the 8 parts and 4 of the 16 parts and so on. I will provide you with an example, you might want to get a piece of paper and pencil. 68 3/16 - 42 5/8 =25 9/16, how did I do this? the book will tell you to find the lowest common denominator, but don't follow the book. I find the easiest common denominator.
If you take 1 from 68 in terms of the denominator then I have 67 16/16 + 3/16= 67 19/16, And then of the 42 5/8, multiply the 5/8 x 2=10/16 or 42 10/16.
Therefore, 68 3/16 - 42 5/8 = 67 19/16 - 42 10/16 = 25 9/16. I hope this help you understand fractions.
