n + 20 - 17 + 13 - n = 20 - 17 + 13 = 3 + 13 = 16
13/20 - 3/5 = 13/20 - 12/20 = 1/20
20 multiplied by 13 is 260.

If the fractions have the same denominator, just add or subtract the numerators. 13/20 - 9/20 = 4/20 2/5 + 1/5 = 3/5
First, subtract 20 and 5. Then take that answer and subtract 13 from it. 20-5-13 15-13 2 The answer is 2
n + 20 - 17 + 13 - n = 20 - 17 + 13 = 3 + 13 = 16
13/20 - 3/5 = 13/20 - 12/20 = 1/20
70 - (20 - 13)
20 multiplied by 13 is 260.

How about: 32+20 = 52
13 over 20 of a meter is equal to 65 centimeters.
If the fractions have the same denominator, just add or subtract the numerators. 13/20 - 9/20 = 4/20 2/5 + 1/5 = 3/5
