Answer: a . 0.0025

b. he divided 1 by 4 to obtain the decimal expression of 1/4, but is still a percentage form.

Step-by-step explanation:

Hi, to write the percentage in decimal form we have to divide it by 100.

(1/4) /100 = 0.0025

The reporter’s error was that he divided 1 by 4 to obtain the decimal expression of 1/4, but is still a percentage form.

1/4 % = 0.25 %  

To fix the error he should have divided the result by 100.

0.25 /100 = 0.0025  

Feel free to ask for more if needed or if you did not understand something.

Would you solve the equation 0.25x + 7 = 1/3x – 8 <br> using fractions or decimals? Explain please.
mamaluj [8]

Answer:

x = 180

Step-by-step explanation:

Solve the value of x :

0.25x + 7 = \frac{1}{3}x - 8

-Combine \frac{1}{3}x and 0.25x by subtracting 0.25x by \frac{1}{3}x :

0.25x - \frac{1}{3}x  + 7 = \frac{1}{3}x - \frac{1}{3}x  - 8

-\frac{1}{12}x + 7 = -8

-Subtract 7 on both sides:

-\frac{1}{12}x + 7 - 7 = -8 - 7

-\frac{1}{12}x = -15

-Multiply both sides by -12, the reciprocal of -\frac{1}{12} :

\frac{-\frac{1}{12}x}{-\frac{1}{12}} = \frac{-15}{-\frac{1}{12}}

x = -15 (-12)

x = 180

Therefore, the value of x is 180.
