7) 1/2, 5/10 = 1/2 because 10÷2=5 and 2÷1=2
8) 1/3, 4/12 = 1/3 because 12÷3=3 and 3÷1=3
9) 1/4, 2/8 = 1/4 because 8÷2=4 and 4÷1=4
10) Simplest Form, 100÷3 still equals 3/100
11) 7/10, 70/100 = 7/10 because the zeros cancel out.
12) Simplest Form, it cannot reduce any further
13) 1/6, because 12/12 (or 1) - 10/12 = 2/12 (or 1/6)
14) 3/4, 8-2=6 meaning that 6 out of 8 kittens are not white, 6/8 = 3/4
15) Simplest form, meaning they can be reduced no further
16) Greatest common factor, this means that there is a number between the numerator and the denominator that they can be reduced by
17) C, because 12/3 = 4

JACKIE COLLECTS DATA THROUGTH THE BASEBALL SEASON AND USED THESE DATA TO DETERMINE THE PROBABILITIES OF DIFFRENT TEAMS PLAYING I

Citrus2011 [14]

In this question, we want to compare several numbers with different denominators and find out which number is the least. To compare this number, we have to change the denominator into the same number by finding the least common multiple (LCM) of the 4 numbers. The factor of each number will be:

3= 3 ^1

5= 5^1

8= 2 * 2 * 2 = 2^3

2= 2^1

We can find the LCM by multiplying a higher exponent of each prime number. The LCM will be:3^1 * 5^1 * 2^3 = 120

Each number will be:

Tiger= 2/3 * 40/40= 80/120

Redbird = 4/5 * 24/24= 96/120

Bulldogs = 3/8 * 15/15 = 45/120

Titans = 1/2 * 60/60 = 60/120

As you can see, the team with the lowest chance to play is Bulldogs = 45/120
