Hi All,
I have recently decided to go back to college and needless to say my math is absolutely horrible. I have a fairly decent understanding of everything up to basic equations but I am stumped at this problem im currently trying to solve for practice. Id appreciate help with an explanation of hows its solved. I already know the answer but I want to work it to become fluent.
Problem is:
3 1/6 + (2 1/3 divided by 3.6)^3
I worked everything out and converted fractions to decimals. Id greatly appreciate any help possible! I want to learn math correctly this time around. I am trying to be disciplined and know why and how I come to an answer instead of just coming to it .
If indeed the given answer is
then the bracket has the value
This is only possible if the number 3.6 in the bracket was originally .
I don't know if you transformed the fraction into 3.6 - then you have made the assumption that an approximate value equals the fraction - or if the 3.6 was given in the first place. If so the authors of the book had made a mistake.
Thanks for the help everyone. Cant believe the worksheet answer key is wrong and led me to more frustration than necessary. I had the right answer and the incorrect key just clogged my mind up now. I knew I was doing something right.
The worksheet I used is here: http://www.math-drills.com/orderofop...cimals_002.pdf (bottom right)
Anyone have any suggestion for better practice?
