Solve for x: 4 over x equals 5 over 10 8 9 20 40

Sati [7]

$\frac{4}{x} =\frac{5}{10}$ [4 over x equals 5 over 10]

Solve for x, so you need to isolate/get x by itself in the equation.

$\frac{4}{x} =\frac{5}{10}$ Multiply x on both sides

$(x)\frac{4}{x}=\frac{5}{10} (x)$

$4=\frac{5}{10} x$ Multiply the inverse of 5/10, which is 10/5, to get rid of the fraction and get x by itself

$(\frac{10}{5} )4=(\frac{10}{5} )\frac{5}{10} x$

$\frac{40}{5} =x$

8 = x
