Computation
Use partial products. 913 X 6 = B
B =5400 + 60 + 18 = 5,478
Write an equation to show 7/9 as a sum of UNIT fractions.
1/9 + 1/9 + 1/9 + 1/9 + 1/9 + 1/9 + 1/9 = 7/9
Teri and her brother each got large boxes of popcorn at the theater. Teri had 5/6 of her popcorn left at the end of the movie. Her brother had only 2/6 of his popcorn left. How much more of his box of popcorn did her brother eat than Teri?
Teri ate 1/6.
Her brother ate 4/6.
4/6 - 1/6 = 3/6 (1/2 in simplest form)

Subtract. 8 4/5 - 2 1/5.
6 3/5
Add 5 1/4 + 3 2/4.

Three friends weigh 92 pounds each. Four others weigh 85 pounds each. How many ounces do these 7 students weigh all together? You may use a calculater. State the conversion first.
There are 16 ounces (oz.) in 1 pound (lb.). 92 X 3 =276, 85 X 4 =340. 276 + 340 = 616
616 X 16 = 9,856 ounces
How many lines of symmetry does a parallelogram (rectangle pulled at corners) have?
What do you call a triangle with all equal sides?
Equilateral Triangle
Use partial products. 83 X 94 = Y
Y= 7200 + 320 + 270 + 12 = 7,802
Add 8/10 + 4/10.
12/10 (improper) or 1 2/10 (mixed number) or
1 1/5 (simplest form for 1 2/10)
A pizza was cut into tenths. Brooke ate 5/10 and Blair ate 4/10. How much pizza is LEFT?
They ate 9/10, so 1/10 is left.
How many lines of symmetry does the capital letter M have?
1
Do the values of a digit increase as you move digits to the left in a number or to the right in a number?
to the left...the digit immediately to the left of a digit is 10 times larger
Subtract. (regroup!) 4 1/4 - 2 3/4 = R
R = 1 2/4 (1 1/2 in simplest form)
Add 4/10 and 60/100.
100/100 or 1 (change 4/10 into 40/100 so denominators are the same)
Two sisters gathered eggs from the chicken coop. Collen collected 9/12 dozen and Mitzi collected 11/12 dozen. How many dozens of eggs did the sisters collect?
9/12 + 11/12 = 20/12 which is 1 and 8/12 dozen (or 1 and 2/3 dozen in simplest form). The whole is 12/12.
How many lines of symmetry does an equilateral triangle have?

What is "the whole" in 3/8?
8/8
Subtract. (regroup!) 5 7/10 - 3 9/10= N
N = 1 8/10 (1 4/5 in simplest form)
Subtract. 7/8 - 1/8 = P
P= 6/8 (3/4 in simplest form)
Two friends cut a candy bar into equal pieces. Harriet ate 1/4 of the pieces, and Nisha at 1/2 of the remaining pieces. Six pieces were left over. How many pieces were in the candy bar originally divided into?
