The answer is A. .3 because do find the percent from a decimal you need to move the decimal point two to the right, so in this case it will be 30 or 30%
34 is 85% of 40
34/.85=40
40*.85= 34

To find the answer, we have to multiply 3/4 by 6.
To do this, we change 6 to 6/1 and multiply straight across.
3/4 x 6/1 = 18/4 = 9/2
9/2 is the same as 4 and 1/2
