BRAINLIEST IF CORRECT!!! How can you show that two fractions are reciprocals?
Subtract the fraction from its reciprocal. Their difference will be 1.
Divide a fraction by its reciprocal. This will show that the quotient is always 1.
Multiply a fraction by its reciprocal to show that their product is always 1.
Add the fraction and its reciprocal. Their sum will be 1.

Multiply a fraction by its reciprocal to show that their product is always 1

Step-by-step explanation:

Multiply a fraction by its reciprocal to show that their product is always 1.

Step-by-step explanation:

say you have 1/2, the recriprocal  is 2/1...

1/2 * 2/1 = 2/2

2/2 = 1

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
