A is 3 1/4 % = 0.03 + 0.25 = 0.28. Is this correct? Why or why not?
So I got .0235 and I don't think this is correct
3% = 0.03
1/4 % = 0.0025
The proposed answer is incorrect, and so is yours. I think, however, that yours is a typo.
To determine if A is equal to 3 1/4%, we need to convert 3 1/4% into a decimal.
To do so, we divide 3 1/4 by 100, since percentages are out of 100.
3 1/4% = 3.25/100
Now let's convert 3.25/100 into a decimal:
3.25/100 = 0.0325
Therefore, 3 1/4% should equal 0.0325 rather than 0.28.
Based on your calculation of 0.0235, it seems like you made an error. The correct value is 0.0325.
To calculate 3 1/4% as a decimal, we can convert it to a fraction first.
1/4% is equal to 1/4 multiplied by 1/100, since the percent symbol represents "per hundred". Multiplying these fractions gives us 1/400.
Adding the whole number, 3, with the fraction 1/400, we have:
3 + 1/400 = 3 + 0.0025 = 3.0025.
Therefore, 3 1/4% is equal to 0.0325 as a decimal, not 0.0235.
So, your calculation of 0.0235 is incorrect.
