Suppose that twice a certain number is 3. Then what is the product of 2019 with the reciprocal of that number

Question

still stuck on this one

Answer 1

Hi Jackson,

Let's use the variable, x ,to represent the unknown number.

Because twice the number is 3, we can write the following equation to represent this: 2x = 3

Now solve this equation for x using inverse operations:

2x = 3

2x/2 = 3/2

x = 3/2

The unknown number is 3/2.

The reciprocal of 3/2 is 2/3.

We can multiply (product) the reciprocal by 2019:

2/3 * 2019 = 4038/3= 1346

The answer to this problem is 1346
