If you have 3/4 cup of flour, how many eights do you have?

You have  and you want to know how many eighths you have

You need to have the denominator to eighths to find out correctly

So 4 times 2 equals 8 but what you do one one side (denominator/bottom) has to be done on the other side (numerator/top) to make it the equal value of the original fraction

So ×≈

So that means that you have 6, eighths

You have 6 eights of flour 

4y - 6 + y^2 - 9 = y^2 + 4y - 15y^2 term terms- termstotal of 3 terms when simplified
