Answer:

Fraction Form: $\frac{2187}{4000000}$

Decimal Form: $0.000547$

Step-by-step explanation:

$=\frac{5}{256} * \frac{3}{5}^1^2 / \frac{3}{5}^5$

$\frac{3}{5}^1^2/\frac{3}{5}^5=\frac{2187}{78125}$

$=\frac{5}{256}*\frac{2187}{78125}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}$

$\frac{5*2187}{256*78125}$

$\mathrm{Factor\:the\:number:\:}\:78125=5\cdot \:15625$

$=\frac{5*2187}{256*5*15625}$

$\mathrm{Cancel\:the\:common\:factor:}\:5$

$=\frac{2187}{256*15625}$

$\mathrm{Multiply\:the\:numbers:}\:256\cdot \:15625=4000000$

$\frac{2187}{4000000}$

The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?

xeze [42]

Answer:

$222$ boys

Step-by-step explanation:

Let $x$ = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.

$\frac{5}{6+5}x = 185$ (number of girls in ninth grade)

$\frac{5}{11}x = 185$

$x=407$

To find for the number of boys, we can use substitution:

$\frac{6}{6+5}x = \frac{6}{11}(407)$

$=222$

∴ There are $222$ boys in the class.

Hope this helps :)

If i walk 4 miles per hour how long will it take to walk a mile

fiasKO [112]

Hi there! The answer is 15 minutes.

Walking 4 miles per hour means that it takes you 60 minutes to walk 4 miles. To find the time it takes you to walk 1 mile, we must divide both sides by 4.

4 miles equals 60 minutes.
1 mile equals 60 / 4 = 15 minutes.

The answer is 15 minutes.
