Integers are both rational and irrational numbers.
True or False?
*Bonus points if you can define an integer
False
Integers are all are all whole numbers including negatives (-3, -2, -1, 0, 1, 2, 3 ...) because of this, they can ONLY be RATIONAL numbers.
The square root of (8 x 2)
4
-------------
8 x 2 = 16, so the square root of 16 is 4 because the product of 4 x 4 = 16
9.205 / 3.5
Set up in long division form and solve
*stop after two decimal places
9.205 is the dividend and goes in the den, 3.5 is the divisor
The quotient is 2.63
Watch those decimals!!!

What type of number is pi?
*bonus points if you can MATHEMATICALLY tell me why
pi is an irrational number because it is a non-repeating decimal
The square root of (225)
. . . Then multiply your answer by twenty nine tenths
square root of 225 = 15, because 15 * 15 =225
. . . then 15 x .29 = 4.35

Tommy likes to play pinball. Tommy works hard at his afterschool job and manages to save $4.38. Tommy goes to the arcade and finds a pinball game that he likes. The game lets him play 3 rounds, and another half of a round if he gets a high score.
If Tommy gets a high score, AND uses all his money playing pinball, how much money will Tommy have spent per each game of pinball?
*Stop after you have reached two decimal spots
$4.38 / 3.5 rounds = $1.25/game
Timmy likes to play arcade games. Timmy works hard at his afterschool job and saves up some money to go to the arcade. Timmy goes to the arcade and finds a basketball game that he likes. The game takes 5 quarters to play. Timmy plays 5 rounds of the basketball game. Timmy puts more money in the game to play a 6th round, but leaves 3/4 of the way in to the game because he forgot something at his house. Luckily he told the arcade owner before he left, and the arcade owner gave him a credit for the time he had left.
How much money did Timmy spend in the arcade?
*Round your answer to the nearest hundredth, and remember the credit!
$1.25 / game
Timmy played 5 games and 3/4 of another one, or 5.75
$1.25 X 5.75 = $6.875, rounded to $6.88
another name for 3.2
*Think of how else we could write this
3 (1/5)
16/5
Three and two tenths
3 (2/10)
What type of decimals are irrational numbers?
Non-Repeating decimals
(pi = 3.14159265359 . . .)
Non-terminating decimals
(3.454545454545. . .)
The square root of
[(5*200) / 10]
. . . then divide by thirty two hundredths
= 100
the square root of 100 = 10
10 / .32 = 31.25 or 31 (1/4)
