Final answer:
To calculate the number of people on the beach, use the given ratio of men to women and the number of women given. Set up a proportion and solve for the unknown variable.
Step-by-step explanation:
To calculate the number of people on the beach, we need to use the given ratio of men to women and the number of women given. The ratio of men to women is 6:7 and there are 28 women. To find the number of men, we can set up a proportion:
6/7 = x/28
Cross multiplying, we get:
6 * 28 = 7 * x
x = 24
Therefore, there are 24 men on the beach. To find the total number of people, we can add the number of men and women:
Total number of people = 24 + 28 = 52
So, the number of people on the beach is 52.
