Question

What would x equal for these two?
15/24 = x/3 & 7/24 = 3/x

Thank you!!!

Answer 1

The first one you have $\frac{15}{24}$=$\frac{x}{3}$ . To solve this you would multiply both sides by 3.

$\frac{45}{24}$=x

Then simplify by dividing the numerator and denominator by 3.

$\frac{15}{8}$=x (or in a mixed fraction 1$\frac{7}{8}$)

The second one you have $\frac{7}{24}$=$\frac{3}{x}$ . To solve this you would multiply both sides by x.

$\frac{7}{24}$x=3

Now you would divide both sides by $\frac{7}{24}$.

x=$\frac{3}{\frac{7}{24}}$

You now then multiply 3 by 24 and then divide by 7.

$\frac{72}{7}$

x=$\frac{72}{7}$ (in a mixed fraction would be 10$\frac{2}{7}$)
