Measurement

So we're through with Day 2 of testing ... just 3 more to go.

Tonight, I handed out a worksheet that reviews adding and subtracting fractions.

Remember: Find the LCM (that's least common multiple) for the denominator, change your fractions accordingly, and then add or subtract.

For instance:

2/3 + 4/8

1) The LCM between 3 and 8 is 24.

2) Change the fractions so the denominators are the same. The new fractions are 16/24 + 12/24

3) Answer is 28/24 or 1 1/6

Still have questions? Ask tomorrow.
