$\frac{5}{3}$

Step-by-step explanation:

$let \:the \: multiplicative \: inverse \: be : x \\ then \: \frac{3}{5 } \times x = 1 \\ \frac{3x}{5} = \frac{1}{1} \\ 3x \times 1= 5 \times 1 \\ 3x = 5 \\ x = \frac{5}{3}$

The answer is 3

Step-by-step explanation:

Let the number to be found be x

The product of a number and 3 is written as

3 × x = 3x

15 minus twice the number is written as

15 - 2x

Now equate the two statements

That's

3x = 15 - 2x

Group like terms

3x + 2x = 15

5x = 15

Divide both sides by 5

the final answer is

x = 3

Hope this helps you
