<p>I suck in math big time, trying to get in the 600s in 5 months.
I don't know if it's me or the book but i have some problems on some questions that are easy for you guys.</p>
<p>Change fractions into percents.
1-) 1/3, I wrote 33.3% but the book said it is " 33 1/8%"</p>
<p>2-)2/3, I wrote 66.6% but the book said it is " 66 2/3%</p>
<p>Change the percents into fractions</p>
<p>38-) 66 2/3%
39-) 1/2%
40-) 2 1/4%</p>
<p>Sorry, this grubber math workbook seems confusing...</p>
<p>Most calculators enable you to convert decimals/percents/fractions somehow; check the manual or look online. Don’t waste time doing it by hand, use your calculator (unless it’s very easy).</p>
<p>I don’t believe that any such question has ever appeared on an SAT. Certainly it would be nice if you knew how to do such conversions, but for SAT preparation this seems like a waste of time to me. </p>
<p>If you are trying to raise your score on the SAT, then you should be practicing using SAT math strategies on SAT math problems. </p>
<p>That said, you can convert a fraction to a decimal simply by performing the division in your calculator.</p>
<p>You can convert a decimal to a fraction by pressing MATH, ENTER, ENTER on your TI-84 (or equivalent) calculator.</p>
<p>You can convert a decimal to a percent by moving the decimal point to the right 2 places (adding in 0’s when necessary)</p>
<p>You can convert a percent to a decimal by moving the decimal point to the left 2 places.</p>
<p>You wrote the following:
1/3, I wrote 33.3% but the book said it is " 33 1/8%"</p>
<p>You probably mean that the book said 33 1/3%.
Technically 33.3% is wrong because it is just an approximation. As a decimal, there should be a tail of infinitely many 3’s. As a fraction, 1/3 is .333333…</p>
