Answer:

multiplicative inverse of 1/2 is 2

Step-by-step explanation:

The multiplicative inverse of a/b is b/a

Because $\frac{a}{b} * \frac{b}{a} =1$

To get multiplicative inverse of any fraction we take the reciprocal of that fraction

Multiplicative inverse of $\frac{1}{2} \ is \ \frac{2}{1}$

2/1 or 2 are same

mamaluj [8]

Question:

Is square root of 1.6875 a rational number ?

Answer:

Square root of 1.6875 a rational number is not a rational number

Solution:

Given that we have to find square root of 1.6875 and determine if it is rational number or not

Let us first find square root of 1.6875

$\sqrt{1.6875} = 1.29903810568$

Let us understand about rational number

A rational number is a number that can be expressed as a fraction (ratio) in the form $\frac{p}{q}$ where p and q are integers and q is not zero.

When a rational number fraction is divided to form a decimal value, it becomes a terminating or repeating decimal.

So the number 1.29903810568 is not a rational number

In other words we can say,

Only the square roots of square numbers are rational. Here 1.6875 is not a perfect square. So it is not rational number
