Question

Please help I'm confused.

Miss Hartley students were working with their mix of raisins and peanuts the class found that 30% of the mix was raisins.Sophie was working with the sample from the mix and counted 42 peanuts in it so he had just poured her simple back into the JAR when she realize that she had counted the wrong thing her Teacher wanted to know how many raisins were in the sample not peanuts

a. Sophie knows that 30% is the same as . Can this be thought of as a ratio? Which two quantities are
being compared in this case? Can you write another equivalent ratio representing the same comparison?
b. Could Sophie write a ratio comparing the number of raisins to peanuts? How could you figure out this
ratio without having to count the peanuts? Discuss this with your team and be ready to explain your
thinking to the class.
c. Find an equivalent ratio that will help Sophie figure out how many raisins should have been in her sample
that contained 42 peanuts.

Answer 1

a) If raisins = 30%
Peanuts = 100 - 30 = 70%
Ratio would be: 30/70 = 3/7

In short, Your Answer for this part would be 3/7

b) She can write the ratio, she need to remember that the number of peanuts must be greater than the number of raisins by 7/3.
[ defined by our ratio expression ]

c) It would be: 3/7 = x/42
x = 42/7 * 3
x = 6 * 3
x = 18

In short, Your Answer would be 18

Hope this helps!
