If you take 3,061,707,850 and divide it by 4 (40%) then 10% of the population is 765,426,962.5. Then you multiply 765,426,962.5 time 10 to reach 100% fo the population, which is 7,654,269,625.

Hope that helps!

Julia completes her homework in an hour. She spends 7/12 of the time doing her math homework and 1/6 of the time practicing her

dsp73

Answer:

15 min

Step-by-step explanation:

Julia spends $\frac{7}{12}$ in math.

and spends $\frac{1}{6}$ in spelling.

Lets make $\frac{1}{6}*2=\frac{2}{12}$ for calculation propuses.

Julia spends $\frac{7}{12} +\frac{2}{6}=\frac{9}{12}$ doing her math and spelling homework.

And lets make $1 hour =\frac{12}{12}$

$\frac{12}{12}-\frac{9}{12} =\frac{3}{12}$ and $\frac{3}{12} / 3 =\frac{1}{4}$

So, Julia spends $\frac{1}{4} hour$ in reading.

If I divide an hour into 4 equal units, each unit equals 15 min, so 1 unit is 15 min.

Julia spends 15 min in reading.
