The question is asking what of the percent forms given equals 0.075.
Recall that the expression % is not really a mathematical expression, but one designed for business.
In math, we use fractions, quotients and their decimal forms to express and use them in calculations.
So, notice that the value of 6 % for example, means the following in math terminology: 6/100, which can be easily converted to its decimal form by moving the decimal point on 6. two places to the left: 0.06
So,now for the questions you have:
3 % is equivalent to the math form: 0.03
12/16 (which is in math form) equals 0.75 when you do the quotient, and that is in percent form 75%
75% is as we mentioned above given by 0.75 in math terms
0.34 (math form) has the following percent form: 34%
0.75 as we saw above is the same as 75% (in business notation)
