## Video transcript

let's do some example questions dealing with ratios so we're told the table shows the number of people waiting in line for different rides at an amusement park so 15 people are waiting in line for the roller coaster four people for the slingshot twelve people waiting in line for the bumper cars and eleven people in line for the roundup what is the ratio of people waiting in line for the roundup to the people waiting in line for the slingshot pause this video and see if you can figure it out so we want to know the ratio of the people waiting in line for the roundup this is the roundup right over here to the right to the number of people waiting in line for the slingshot so there's 11 people waiting in line for the roundup and there are four people waiting in line for the slingshot so the ratio is 11 to 4 or for every 11 people in line for the roundup there are 4 people waiting in line for the slingshot let's do another example Katie loves to read in the last few months she has read three graphic novels two mysteries for science fiction novels and 21 comic books what is the ratio of sci-fi novels to comic books so once again pause this video and try to work it out on your own all right so we want to know the ratio of sci-fi novels so she has four sci-fi novels the ratio of that to comic books she has 21 comic books so the ratio is for every four sci-fi novels she has 21 comic books don't do that that other color she has 21 comic books so the ratio is 4 to 21 the ratio of sci-fi novels to comic books for sci-fi novels for every 21 comic books let's do one more example this is strangely fun what is the ratio of apples to bananas pause this video and try to figure it out so let's see there are 1 2 3 apples so for every 3 apples how many bananas are there well there is 1 2 3 4 bananas so the ratio of apples to the ratio of apples to bananas is 3 apples for every 4 bananas in order matters if they set the ratio of bananas to apples then this would be 4 to 3 but they say apples to bananas 3 2 4 3 apples for every 4 bananas
