Rose has a playlist with 40 rock songs and 28 country songs. What is the ratio of country songs to rock songs on the playlist?
cupoosta [38]
<em>The answer is 10:7, 10/7, 10 to 7. Whichever it's asking for. As long as you know the ratio is 10 rock songs to 7 country songs.
</em>
<em /><u>
</u><em />This problem can be a simple fraction simplification problem. Here's what I mean:
<em>
</em>
<em />So, we have 40 rock songs and 28 country songs. Let's put that into a fraction:
<em>
</em>
\frac{40}{28}
<em>
</em>To simplify this as much as possible, all we have to do is find the greatest common multiple and divide it by both numbers. the GCF is 4, so all you have to do is divide 40 by 4 and 28 by 4 to get your ratios.
<em>
I hope this helped!!

A group of 48 senior citizens attended a baseball game. The number of women in attendance was 12 more than the number of men. Ho
Sergio [31]

Answer:

18 men attended the baseball game, and 30 women attended the baseball game.

Step-by-step explanation:

Let the number of men in attendance be x and the number of women in attendance be x+12.

No. of men + <em>No. of women</em> = <u>48 </u>

x +<em> x + 12</em> = <u>48</u>

2x + 12 = 48

2x = 48 - 12

    = 36

x = 36 ÷ 2

x = 18

x+12: 18 + 12 = 30
