Question

A butterfly can fly 1/5 in a mile. How long would it take the butterfly to fly 1/8 mile

Answer 1

Answer:

$x = \frac{1}{40}$

Explanation:

Given

$\frac{1}{5} = 1\ mile$

Required

How long to fly $\frac{1}{8} \ mile$

Represent the required parameter with x

i.e.

$x = \frac{1}{8}\ mile$

Recall that

$\frac{1}{5} = 1\ mile$

So: we have:

$\frac{1}{5} = 1\ mile$

$x = \frac{1}{8}\ mile$

Cross Multiply

$x * 1\ mile = \frac{1}{5} * \frac{1}{8}\ mile$

$x = \frac{1}{5} * \frac{1}{8}$

$x = \frac{1}{40}$

Hence;

It'll take the butterfly $\frac{1}{40}$ in a mile
