Question

56 is 70 precent of what number

Answer 1

to solve this problem, you can use the equation 56=70/100*x
and you have to solve for x

first simplify 70/100 by diving 10 to both denominator and numerator.
Which become 7/10

So the equation is now 56=7/10*x

Now, to solve for x, you have to move the variable (x) on one side and numbers at the other, equal sign being the fence.

so, with the equation 56=7/10*x, you should multiply 10/7 to both sides to make 7/10 to 1. Which becomes
80=x

Therefore, 56 is 70 percent of 80.

In case you didn't understand, sorry for my bad english. Here is my work
56 is 70 percent of what number?----> 56=70/100 of x

of=*(multiply)

56=70/100*x
56=7x/10
56*10/7=7x/10*10/7
80=x

tada!~

Answer 2

so percent means parts out of 100 so
70%=70/100=7/10
56=7/10 of x or
56=7/10x
multiply both sides by 10/7 to clear fraction (7/10 times 10/7=70/70=1)
56 times 10/7=x
560/7=x
80=x

the number is 80
