if y is 90 % greater than x, than x is what % less than y?	Select the correct option
A) 35.7 %	B) 39.8 %	C) 43.2 %	D) 47.4 %	E) 51.2 %
<gadget id="calculator">90 + 100</gadget>
<output>190</output>

<gadget id="calculator">90 / 190</gadget>
<output>9/19 = around 0.473684</output>

<gadget id="calculator">(9/19) * 100</gadget>
<output>900/19 = around 47.368421</output>

<result>D</result>
if y is 90 % greater than x, than x is what % less than y?
multiply(divide(90, add(90, const_100)), const_100)
"y = 1.9 x x = y / 1.9 = 10 y / 19 x is 9 / 19 less which is 47.4 % less than y . the answer is d ."
