501 Questions to Master the GED® Mathematical Reasoning Test
 28. The correct answer is choice d. The key word difference means 
subtract. Begin by writing the numbers one over the other, lining 
up the decimal points.
 7.90
 –0.26
 Because 6 is larger than 0 in the hundredths place, borrow 10 from 
the 9 in the tenths place. This makes the 9 an 8 and the 0 a 10.
 7.90
–0.26
8 10
 –0.26
 Now subtract the columns.
 7.90
–0.26
7.64
8 10
 –0.26
 7.90
 The answer is 7.64.
 29. The correct answer is choice d. Convert the fraction to a decimal 
by dividing 5 by 8:
 5 ÷ 8 = 0.625
 Cecil lives 1 5__
8 miles from his school, so place a 1 in the ones place of 
the decimal—1.625.
 30. The correct answer is choice a. The fractions can easily be con-
verted to decimals. The first decimal place to the right of the decimal 
point is the tenths place. So 3__
10 (or three-tenths) = 0.3, and 7 3__
10 = 7.3. 
The fraction 3__
5 can be converted into tenths: 3__
5 × 2__
2 = 6__
10. Thus, 6 3__
5 = 
6.6. Now that all of the numbers are in the same form, they can be 
easily ordered from least to greatest.
 Choice b is incorrect because 6.8 is not less than 6 3__
5 .
 Choice c is incorrect because the numbers are ordered from greatest 
to least.
 Choice d is incorrect because 7 3__
10 is not the greatest number.
