Question

write a part to part and a part to whole ratio for each problem situation of the 250 students surveyed, 142 prefer carrots and 97 prefer peas

Answer 1

∵ There are 142 who prefer carrots

∵ There are 250 all

∴ The fraction represents who prefer carrots is

`(142)/(250)`

We must simplify the fraction by divide up and down by the same number until getting the simplest form

∵ 142 and 250 can divide by 2

`\therefore((142)/(2))/((250)/(2))=(71)/(125)`

∵ 71 and 125 can not divide by any number

∴ The fraction is 71/125

∴

∵ There are 97 who prefer peas

∵ There 250 all

∴ The fraction represents who prefer peas is

`(97)/(250)`

∵ 97 and 250 can not divide by the same number

∴ The fraction is 97/250

∴ The ratio is 97: 250
