Daily Scribe

Today in math we reviewed for a test on friday. The test will contain numerous things and today we reviewd adding and subtracting fractions, and mixed numbers. You could either stay at the smart bored and do problems, or you and a partner could work on problems in your textbook.An example of subtracting fractions is 2 and 1/2 - 1 3/4=2 2/4 -1 3/4. You had to make it into the same denominator and now you have to make mixed numbers. The mixed numbers would be 10/4 - 7/4= 3/4, so 3/4 would be your answer. We also learned how to subtract with varibles. The equation would be 12/b - 5/b. Since they have the same denominator you with minus the numerators and leave the denominator as c. That would make your answer to be 7/b. This would be the same rule for adding with varibles.
