A company is giving gifts to its employees. Employees can choose a gift card, hat, or candy. The table shows the gift chosen by
Paraphin [41]

Answer:

360 Employees

Step-by-step explanation:

Number of employees who chose gift card / Number of total employees

= 90 / 150

Now, we have to figure out in x / 600 when the x represents the number of employees choosing gift card when there are 600 employees in total.

90 / 150, x / 600

-> cross multiply

54,000 = 150x

Therefore 360 = x.

another way:

(multiply the total number of employees in both ratios) 600 / 150 = 4

Now we multiply 4 by 90 (number of employees choosing gift card)

4*90 = 360
