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!~
