Answer:

4.62%

Explanation:

Ask yourself: "3 is what percent of 65?" and solve.

Percentage solution with steps:

Step 1: We make the assumption that 65 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%=65.

Step 4: In the same vein, x%=3.

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

100%=65(1)

x%=3(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

100% / x% =65 / 3

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

x% / 100% =3 / 65

---> x = 4.62%

Therefore, 3 is 4.62% of 65.
