Question

Simplify the equation 28st/-4t

Answer 1

We can simplify both the numeric and literal parts.

It could be useful to rewrite the fraction as follows, to make clear what we're simplifying with what:

$\dfrac{28st}{-4t} = -\dfrac{7\cdot 4}{4}\cdot s \cdot \dfrac{t}{t}= -7\dfrac{4}{4}\cdot s \cdot \dfrac{t}{t}$

The fractions 4/4 and t/t simplify to 1, since the numerator and denominator are the same. So, we're left with

$\dfrac{28st}{-4t} =-7s$
