If the pool has 18 married and 22 not married, this means there are 40 people total
this means there’s a 18/40 probability that people who are married will be chosen
18/40 = 2/5
There is a 22/40 probability people who are un married will be chosen
22/40 = 11/20
Question 1:
think about which one Arnold has already cut the most.... he cut the green string into 6 equal size lengths. the blue he cut into 2 and the red he cut into 3 and both of those can go into 6 so six is the answer.
Question2:
same concept as question one. You're learning the basics to fractions, or division. what is the largest amount a gronola bar is cut into..... 12 pieces. But 8 doesn't divide into 12 does it so what can 12 multiply into that 8 does also..... 12x2=24 and 8x3=24 also. 4x6=24 too therefore the smallest number of equal size pieces each tray can have is 24 pieces.
Question 3:
least common denominator means the bottom number in each fraction is multiplied into the smallest number all the bottom numbers can equal. 1/2, 3/5, and 9/15... what number can 2, 5, and 15 all be multiplied into. look at the biggest number 15 it is not divisable by 2 so multiply it by 2 15x2=30. 30 is divisable by 2 and by 5 so it is the least common denominator. so double it 30x2=60.
A because it represents it the right way
Let the final score of White Sox = x
the final score of Marlins = y
White Sox won by 2 runs. Thus
x = y +2
White Sox had twice as many runs as Marlins
x = 2y
From the equations,
2y = y + 2
=> 2y - y = 2
=> y = 2
x = 2y = 2×2 = 4
Hence, final score of
White Sox = 4
Marlins = 2
