Answer:
2) is not proportional, 3) is not proportional, 5) is proportional, 6) is not proportional.
Step-by-step explanation:
Number 2 is not proportional since it doesn't go through the origin on the graph and the line is not a straight line.
Number 3 does not go through the origin, so number 3 is also not proportional.
Number 5 is proportional since when you divide y by x, it is always 7.
Number 6 is not proportional because when you divide y by x or x by y there are not the same answers.
Yes, for fractions you can multiply the denominator by the numerator. For square roots you can use the square root button.
There would be 80 women.
Here's the work:
120 divided by 3 = 40
If the ratio is 3:2, there is always one less woman then men, so you subtract the 40 men in a group and you get your answer of 80
