Question

Jordan was given the expression 2 x 2-3 x 25.How should he write the expression as a fraction?

Answer 1

Answer:

He should multiply both the numerator and denominator by 5 to have:

$-\frac{55}{5}$

Explanation:

Given the expression

$2\times2-3\times5$

We want to write this as a fraction.

First, let us evaluate the expression, so that we can have a single number which can be converted to a fraction

$\begin{gathered} 4-15 \\ =-11 \end{gathered}$

Now, consider

$-11=-\frac{11}{1}$

Multiply the numerator and denominator by any quantity, we have a fraction.

Choose any number to multiply, as long as what you multiply by the numerator is what you multiply by the denominator, the answer is okay.

Choose 5. Multiplying both the numerator and the denominator by 5

$\begin{gathered} -\frac{11\times5}{1\times5} \\ \\ =-\frac{55}{5} \end{gathered}$

This is now a fraction!
