Once they start repeating, you've reached the end of the line of new factor pairs.
Is this number prime or composite?
63
If its composite, what are its factors
Composite!
The factor pairs of 63 are (1, 63), (3, 21) and (7, 9).
1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10=??
1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10+1/10= 12/10
which you MUST simplify into 1 and 2/10
Andrew and Ibrahim played video games. Andrew scored 5,397 points in Level 1 and 6,928 points in Level 2. Ibrahim scored 4,808 points in Level 1 and 5,219 points in Level 2. How many more points did Andrew score than Ibrahim?
(5397 + 6928) – (4808 + 5219) = p
12,325 – 10,027 = p
p = 2,298 points
Andrew scores 2298 more points than Ibrahim
True or False

Is 111 a Prime or Composite number?
If its Composite, what are its factor pairs?
Composite!
Its factor pairs are (1, 111), (3, 37)
1/18 + 3/9 BECOMES 2/18 + 6/18
NO! For each fraction you have to do the same to the numerator that you did to its denominator
SO
1/18 would stay 1/18 and 3/9 would become 6/18
Elevation Station charges $13 for a 1-hour jump and $20 for a 2-hour jump. If 68 people paid for a 1-hour jump and 49 people paid for a 2-hour jump, how much money did Elevation Station make in all?
(13 x 68) + (20 x 49) = m
884 + 980 = m
m = $1,864
Elevation Station made $1,864 in all

105, 220, 325, 1225, 10500
5!
which of these is NOT a prime number?
11, 23, 32, 37, 41, 53, 58, 67, 71, 79, 89, 97
32 and 58 are not prime numbers!
The factor pairs of 32 are (1, 32), (2, 16)and (4, 8).
The factor pairs of 58 are (1, 58) and (2, 29)
Solve the Problem!
5/6+ 6/7=???
6 and 7 share the multiple 42
so 5/6 becomes 35/42 and 6/7 becomes 36/42
35/42 + 36/42= 71/42
Which SIMPLIFES into 1 29/42
The penguin nursery is open two times a day: 2/3 or an hour at noon and 5/12 of an hour in the afternoon. How much time is the penguin nursery open every day?
2/3 +5/12 =8/12 + 5/12= 13/12
that SIMPLIFIES into 1 1/12
The penguin nursery opens 1 1/12 hours.
Which landmass is bigger, Greenland or Africa?
Africa is MUCH larger than Greenland, despite what the maps say.
TIME CHALLENGE
you have 1 minute to figure out all of the factor pairs of these numbers
45, 36, 71
45- (1, 45), (3, 15), and (5, 9)
36-(1, 36), (2, 18), (3, 12), (4, 9), and (6, 6)
71- (71,1)
Will the product of two prime numbers also be prime?
NO
The product of two primes can't be a prime because it violates the definition of the prime number as it will be divided by the prime numbers which are multiplied rather than 1 and the number itself. So the number is not prime it will become a composite number instead.
Solve this problem!
4/8+3/9+1/8+2/9
4/8+1/8=5/8 and 3/9+2/9=5/9
5/8+5/9 BECOMES 40/72 + 45/72= 85/72
which SIMPLIFIES into 1 13/72
Two kinds of fish can be found in a small tank that is 5 1/7 feet long. The blue fish is 2/15 feet long and the orange fish is 7/10 feet long.
How much longer is the orange fish?
5 and 1/7 is USELESS information
7/10- 2/15= 21/30-4/30= 17/30
The orange fish is 17/30 feet longer than the blue fish
