Micah is buying candy for the Halloween party. There will be 13 adults and 17 children attending the party. He plans to give out 3 pieces of candy for
each adult and 1 piece for each child. There are 8 pieces of candy in each
package. How many packages of candy will Micah need to buy in order to
have enough candy for the people attending the party?
7, because (13 x 3 + 17) + 8 - 7
O 15, because (13+ 17 x 4) + 8 - 15
O 28, because (13 x 17 +3) + 8 - 28
80, because (13 + 17) 8+3 - 80
O

what is the question?

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
