Select all that apply. Which of the following shows that 5/6 = 15/18 is a proportion?
5 • 15 = 6 • 18
5 • 18 = 6 • 15
5.6/6.3 = 5/18
5+10/6+12 = 15/18

Answers

Answer:

5 · 18 = 6 · 15

Step-by-step explanation:

5/6 = 15/18

If this is proportional, then if we flip it, it should work,

To do this, we'll need to do the opposite to both sides

Which we'll multiply 15 by that 6 under the 5, and the 5 by the 18 which was under the 15

So;

5 · 18 = 15 · 6

Which can be rewritten as

5 · 18 = 6 · 15

Hope that helps :)

hector's bag contains three kinds of marbles. he is 2 times more likely to randomly select a white marble than a striped marble. he is equally likely to select a white marble as a dotted marble. of the original bag of 10 marbles is tripled, keeping the ratios of striped, dotted, and white marbles the same, how many of each type of marble are in the bag?

Answers

Answer: 12 white, 12 dotted and 6 striped

Step-by-step explanation:

There are 10 marbles. There are twice as many white marbles than striped marbles, and there are the same amount of white marbles and dotted marbles.

Trial and error concludes that there are 4 white marbles, 4 dotted marbles and 2 striped. Then, you have to triple them (multiply by 3)

4x3=12

4x3=12

2x3=6

12 white, 12 dotted and 6 striped
