13/20 - 3/5 = 13/20 - 12/20 = 1/20
To get 5 using the numbers 19, 2, 6, and 3, you can subtract 6 from 19 to get 13, then subtract 3 from 13 to get 10, and finally subtract 2 from 10 to get 8. So, you cannot get 5 using these specific numbers.
7 ft 3 in. You can subtract 2 in from 5 in to get 3 in, then subtract 6 ft from 13 ft to get 7 ft and add the two results to get 7'3".
First, subtract 20 and 5. Then take that answer and subtract 13 from it. 20-5-13 15-13 2 The answer is 2
3x + 8 = -5 Subtract 8 from both sides: 3x = -5 - 8 = -13 Divide both sides by 3: x = -13/3
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
Multiply by four and then subtract three.
If 13 and 518 are both denominators, the LCD is 6734 If that's 1/3 and 5/18, the LCD is 18 and you can change 1/3 to 6/18
