Someone help me with this homework question?

Question

ok does anyone please knows how to solve this math question?:

At Sabatini's Department store, the ratio of salespeople to managers is 10:3. If Sabatini's currently has 420 salespeople, how many managers are there?

Answer 1

126
420/10 x 3

Answer 2

think of the ratio as a fraction - 10/13 of the people are salespeople, and 3/13 of them are managers. If you divide 420 by 10, you get 42 (since that's 10/13 of the total). Multiple 42 * 3 to get 126 managers.

To check, does 126/566 = 3/13? You bet.
Does 420/566 = 10/13? yes.

Answer 3

For every 10 salespeople there are 3 managers...420 salespeople divided by 10 = 42 units of salespeople.

42 units of salespeople x 3 managers per unit = 126 managers

Sabatini's has 420 salespeople and 126 managers.

Answer 4

126

divide number of sales people by 10: 420/10=42
(since there are three managers for every 10 salespeople)
Now multiply 42 x 3 = 126

Answer 5

I'm starting my lunch break, so I will be glad to help you.

Remember, a ratio is just a fraction. Like RATIOnal numbers. The easiest way to solve this is to set the ratios equal to each other, cross multiply, and solve for x.

420|x = 10|3

Cross multiply

420*3 = 10x

1260=10x

Solve for x

x=126

126 managers.

You can check this by reducing the fraction.

420|126 == (42*10)|(42*3)== 10|3

The ratios work out.

Answer 6

You take 420 and divide it by 10, which = 42, and then take 42 and multiply it X 3 and that = 126. It's pretty simple. I had my share of problems with percentages when I was in school too. It will come to you.

Answer 7

divide 420 by 10 and get the 42

42 x 3 = 126 managers

Answer 8

126
