Answer:
3/3 (1)
Step-by-step explanation:
1/3 plus 2/3 is 3/3.
Since the denominators are the same, you just keep the number the same and add the numerators (top numbers)
The ratio of pop songs to rock songs you download is 5:4, and 40 are pop songs. You want to find out how many rock songs there are.
First, add the ratios together: 5+4=9. This means that 9 will be your denominator, so 5/9 songs are pop and 4/9 songs are rock.
Now you know that pop songs account for 5/9 of the songs, this means that 40 is 5/9 of the total songs.
To find out how much 4/9 is, you need to divide 40 by 5 to get 1/9 and times that number by 4 to get 4/9:
40÷5=8×4=32 songs are rock songs
That's correct! :) Well done! (M=30)
so M-9=21
would just be 30 - 9 = 21
