Think of when you are given an equation in which a number is being divided by a fraction. Any time you do so, you are taught to flip the fraction (the denominator) and then multiply, instead of divide, by the numerator:
 
5/(2/3) --> 5 x (3/2) --> 15/2 

A rational number, by definition, is not a fraction. However, you can easily turn any whole number into a fraction by placing it over 1. So, if you were to divide a number by a fraction whose denominator is 1, you would then flip the fraction (the denominator) and multiply it by the numerator. By definition, you would be multiplying by the reciprocal of the previous fraction, because the reciprocal of any whole number is that number over 1:

5/4 = 5/(4/1)
5/(4/1) --> 5 x (1/4)

In this case, 1/4 is the reciprocal of 4.

That's why you're being told to flip the second fraction. You're recognizing that dividing by a number is the same as multiplying by the reciprocal. ... Now to multiply fractions, we simply multiply the numerators to get the new numerator and multiply the denominators to get the new denominator.

Explanation:

A figures of speech is also referred to as figurative language and it can be defined as a deliberate and specific construction or use of language by writers, authors or speakers to create a special effect in their speech or literary work (write-ups).

In English literature, the main purpose of the figures of speech (figurative language) is to convey more information and enable the readers or listeners have a deeper understanding of a literary work. Some examples of the figures of speech (figurative language) used in literature are simile, paradox, metaphor, apostrophe, hyperbole, personification, etc.

Personification involves intentionally attributing life, human characteristics (qualities) or feelings and emotions to animate and inanimate objects i.e non-living things.

An example of personification in the excerpt above is, The lizard uses a sword to cut crops. It's practically impossible for a lizard or any other animal to use a sword in cutting crops because they lack the sense, ability and composure to do so.
