Question

Which of the following expressions could be used to find 80% of X (the lines are there to show the different expressions)

Answer 1

Answer:

80/100 times x =>  $\frac{80}{100}*x$

(0.8) times x => $(0.8)*x$

4/5 times x => $\frac{4}{5}*x$

8/10 times x => $\frac{8}{10}*x$

Step-by-step explanation:

80% of x means 80 ÷ 100 × x

that is: $\frac{80}{100}*x = \frac{8}{10}*x = \frac{4}{5}*x = (0.8)*x$

Therefore, the expressions that can be used to find 80% of x are:

80/100 times x =>  $\frac{80}{100}*x$

(0.8) times x => $(0.8)*x$

4/5 times x => $\frac{4}{5}*x$

8/10 times x => $\frac{8}{10}*x$
