How to solve a equation like: 2m = -2/3

adell [148]

Answer:

$m = -\frac{4}{3}$

Step-by-step explanation:

$2m = -\frac{2}{3}$

Divide both sides by 2 to get just m

$\frac{2m}{2} = \frac{-\frac{2}{3}}{2}$

You can't divide a fraction by a number so you do kcf (keep it, change it, flip it)

$m = -\frac{2}{3} x \frac{2}{1}$

$m = -\frac{4}{3}$

I read 1/3 of a book in an hour. How much more of the book will I read in 2 1/5 hours

Verizon [17]

Answer:

Step-by-step explanation:

To find the number of pages of the book in the given hour:

To find the number of pages in 2 1/5 hours, multiply the number of pages read in 1 hour by 2 1/5 hours.

$\sf \text{ Number of pages read in 2 $\dfrac{1}{5}$ hours = $\dfrac{1}{3}*2\dfrac{1}{5}$ }$

$\sf = \dfrac{1}{3}*\dfrac{11}{5}\\\\=\dfrac{11}{15}$

$\sf \text{Number of pages read more in 2 $\dfrac{1}{5}$ hours = $\dfrac{11}{15}-\dfrac{1}{3}$}$

$\sf =\dfrac{11}{15}-\dfrac{1*5}{3*5}\\\\=\dfrac{11}{15}-\dfrac{5}{15}\\\\=\dfrac{6}{15}$
