to solve this problem, you can use the equation 56=70/100x
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=7/10x
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=7/10x, 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=70/100x
56=7x/10
5610/7=7x/10*10/7
80=x
tada!~
