Which of the fractions is in lowest terms and is equivalent to -1.25

hjlf

Answer:

The lowest terms equivalent to - 1.25 = - $\frac{5}{4}$

Step-by-step explanation:

- 1.25 = - $1\frac{25}{100}$

= - ( 1 × 100 +25) ÷ 100

= -( $\frac{125}{100}$ ) × ( $\frac{5}{5}$

= - $\frac{25}{20}$

= - ( $\frac{25}{20}$ ) × ( $\frac{5}{5}$

= - $\frac{5}{4}$

Factor the expression.

grigory [225]

Hey!

First, let's write the problem,
$4r^2-64$
Factor out the common term, which is 4,
$=4\left(r^2-16\right)$
Then, let's factor this part: $r^2-16$
We are going to factor it using the difference of squares rule.
$=\left(r+4\right)\left(r-4\right)$
Our final factored answer would be,
$=4\left(r+4\right)\left(r-4\right)$

Thanks!
