you would set up this problem by saying 70% over 100 as a fraction and 140 OVER x and cross multiply
140 70
____ ___
x 100 70x=14,000
Divide x= number DONE
Let
x-------> the number
we know that
\(70\) % is equal to \(\frac{70}{100}\)
\(\frac{70}{100} *x=140\)
multiply by \(100\) both sides
\(70*x=14000\)
divide by \(70\) both sides
\(x=200\)
the answer is
the number is \(200\)
