At the talent show,dancers outnumber singers by a ratio of 13 to 7.If there are 52 dancers at the talent show

please help. ten points. im very grateful

52 × 7/13 = 28 singers

13 * 4 = 52 dancers

So what you do to the number (13) you must do to the other number (7)

Meaning

7 * 4 = 28 singers
The question is not clear.
If you want me to work out the singers then the answer is 28 singers
If you want to total amount then it's
52 + 28 = 80
