Question

is 0.7 the multiplicative inverse of 1 3/7

Answer 1

Answer:

Yes

Step-by-step explanation:

We know that if we Multiply the given numbers and the result will be 1. then we can say that the number is its multiplicative inverse.

Given numbers are : $0.7 and 1\frac{3}{7}$

Solution:

we can write $1\frac{3}{7}$ as $\frac{10}{7}$   ( if we multiply 1x7 and add 3 to it)

Also, we can write $0.7 as \frac{7}{10}$

So, the numbers are

$\frac{7}{10} and \frac{10}{7}$

By Multiplying Both the numbers, we get

$\frac{7}{10}$ x$\frac{10}{7}$ $=1$

Hence Proved, that 0.7 is the multiplicative inverse of $1\frac{3}{7}$.

Answer 2

Yes, $0.7$ is the multiplicative inverse of $1 \frac{3}{7}$.

Step-by-step explanation:

We are aware that if we multiply the supplied numbers and the answer is 1, we can infer that the result is the multiplicative inverse of the original number.

Given numbers - $0.7$ and $1\frac{3}{7}$

Write $1\frac{3}{7}$ as $\frac{10}{7}$.

Similarly, write $0.7$ as $\frac{7}{10}$.

Now, the numbers are $\frac{10}{7}$ and $\frac{7}{10}$.

Multiply both the numbers:

$\frac{10}{7}$ × $\frac{7}{10} = 1$

Hence proved, $0.7$ is the multiplicative inverse of $1 \frac{3}{7}$.
