A survey indicated that 3 out of 5 doctors used brand X aspirin. If 2000 doctors were surveyed, how many used brand X?, I'm not understanding this question.
One way to solve this is to set up a proportion. Cross multiply and solve for x.
3/5 = x/2000

Certainly! To solve the equation x/2 = 5/15, you can follow these steps:
Step 1: Multiply both sides of the equation by 2 to eliminate the fraction on the left side. This gives you: (x/2) * 2 = (5/15) * 2.
Step 2: Simplify the equation by canceling out the 2 on the left side, which leaves you with x = (5/15) * 2.
Step 3: Multiply the fraction (5/15) by 2 to get the value of x. This gives you x = 10/15.
Step 4: Simplify the fraction 10/15 by dividing both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of 10 and 15 is 5, so you can simplify the fraction to x = 2/3.
So, the solution to the equation x/2 = 5/15 is x = 2/3.
