In a company, 60% of workers are men. If 1,380 women work for the company, how many workers are there in all? Show two different ways you can solve this problem.

3450 workers in total

Step-by-step explanation:

since 60% is men the 40% are the 1380 women

1 way:

divide 40 and 1380 by 4 to find how many workers in 10%

- 40/4=10 1380/4=345 -> 10% are 345 workers

10%*10=100% 345*10=3450 workers in total

second way:

40%/2 = 20%    1380/2=690

100/20=5          690*5=3450

0.32

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.
