Question

Is 0.15 the multiplicative inverse of -6 2/3

Answer 1

Answer:

No

Step-by-step explanation:

0.15= 15/100

-6 2/3 = -20/3

Multiplicative inverse of:

0.15 = 100/23

-6 2/3 = -3/20

So, 0.15 is not the multiplicative inverse of -6 2/3.

Answer 2

Answer:

0.15 is not the multiplicative inverse of $-6\frac{2}{3}$.

Step-by-step explanation:

Explanation:

First, we know what is multiplicative inverse.

• Multiplicative inverse  - A number that when multiplied by a number x results in the multiplicative identity, 1, is known as a multiplicative inverse or reciprocal, indicated by $\frac{1}{x}$ or $x^{-1}$.

• A fraction $\frac{a}{b}$ has a multiplicative inverse of $\frac{b}{a}$. Divide 1 by the real number to obtain the multiplicative inverse of the number.

Step 1:

From the question we have, $-6\frac{2}{3}$

This can be written as, $\frac{-20}{3}$

So, the multiplicative inverse of $\frac{-20}{3}$ is $\frac{-3}{20}$ = -0.15

Therefore, 0.15 is not  equal to  -0.15.

Final answer:

Hence, 0.15 is not the multiplicative inverse of $-6\frac{2}{3}$.
