Answer:

The answer is B.

Step-by-step explanation:

<em>A true proportion is a set of ratios that equal each other.</em>

<em> </em>For example, 1:2=2:4 is a proportion.

As we look through the list, we observe only B equals each other. Imagine 3:4 and 9:12 as a fraction. (¾ and 9/12). If we reduce 9/12, we get ¾. Thus, 3:4 = 9:12:)

I hope this helps!

miv72 [106K]

Answer:

  • 12 large rooms
  • 8 small rooms

Step-by-step explanation:

If all were small rooms, 40 guests could be accommodated. Each large room accommodates 1 more guest, so there must be 52 -40 = 12 large rooms. The remaining 20 -12 = 8 rooms are small rooms.

Jayden reserved 12 large and 8 small rooms.

__

If you can't think without an equation, let x represent the number of large rooms. Then the number of guests accommodated is ...

  3x + 2(20-x) = 52

  x + 40 = 52

  x = 52 -40 = 12 . . . . . . .number of large rooms

  (20-x) = 20-12 = 8 . . . . number of small rooms
