**2 + 3 + 0 =5**. 1 3/4 rounds to 2, 3 3/16, and 1/9 round to 0.

(S)

3 7/10 rounds to

**4**, 4 1/15 =

**4**, and 2 2/13=

**2**. Making this

**4+4+2 = 10**

**(D) **Diane went salmon fishing with her father. Diane caught one that weighed 16 3/8 lb. Her father caught one that weighed 10 1/16 lb. About how much heavier was Diane's fish?simple sentence answer: Diane's fish was about 6 lb heavier.

We round 16 3/8 to 16, then subtract (since we're trying to find the difference) 10(10 1/16). **16 - 10 = 6**

**(T) 11 6/7 + (13 1/5 - 3 1/11)**

First, do the work that is in the brackets: **13 1/5** rounds to **13**, and** 3 1/11 = 3**

**13 - 3 = 10**

**11 6/7 = 12**

**12 + 10 = 22**

We also discussed an easier way to find the LCD of fractions like this:

**3 7/10 + 4 1/15 + 2 2/13**

You can multiply all the denominators together ( in this case you get 1950), or you can find the prime factors of the denominators.

Now we get rid of any doubles, that is why one of the 5s are crossed out. Now if you multiply them all together, it will equal 390, their common denominator. But it doesn't ALWAYS work. If you have time, Mr. Harbeck told us to search prime factors and LCDs.

Well, thanks so much for reading. I hope this helped (sorry for being so late!). For the next scribe, I choose ELMANE :)
