Question

116⅔%of 180+240%of 450=?​

Answer 1

Answer:

Step 1: We make the assumption that 450 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=450$.

Step 4: In the same vein, $x\%=240$.

Step 5: This gives us a pair of simple equations:

$100\%=450(1)$.

$x\%=240(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{450}{240}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

Answer 2

240×450/100=1080+35×6=1290
