10 is what percent of 60

Alona [7]

Is means equal
x percent is x/100
of means multiplication

So translating what you were given:

$\sf{10=\frac{x}{100}\times60}$

Solve for x

$\sf{10=\frac{60x}{100}}$

Simplify it

$\sf{10=\frac{3x}{5}}$

Multiply both sides by 5/3 to isolate x

$\sf{x=\frac{50}{3}}$

Your final answer is

$\huge{\boxed{\bf{10~is~16.67~percent~of~60}}}$
