Answer:

Step-by-step explanation:

Multiplicative reciprocal of x is 1/x

Eg: Multiplicative reciprocal of 4 is 1/4

Multiplicative reciprocal of 1/8 = 8/1 = 8

Multiplicative reciprocal of 89 is 1/89

When we multiply a number and its Multiplicative reciprocal , the result will be 1

4*1/4 = 1

Answer:

14 and 4/1000 or 14004/1000

Step-by-step explanation:

1*10+3*1+4*(1/1000)

First i like to separate the equation by PEMDAS or order of operations. First is parentheses, which is the fraction. Then is exponents. There is none. Then multiplication and division so u solve 1*10, 3*1 and 4*1/1000.

This is the updated equation: 10+4+(4/1000)

Next you do subtraction and addition. The order does not matter if there's only addition. If there is subtraction u solve by the order of the equation. SO in this step we solve 10+4+(4/1000)

Here is the updated version: 14+(4/1000)

Then u add that which is 14 and 4/1000 or you can do 14004/1000
