56 is 70 precent of what number
2 answers:
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!~
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
