Let's guess and check.
Let's try 8
2 × 8 = 16
3 × 8 = 24
4 × 8 = 32
16 + 24 + 32 = 72 ==> too high
Let's try 6,
2 × 6 = 12
3 × 6 = 18
4 × 6 = 24
12 + 18 + 24 = 54 ==> perfect
Wow, I did not think I'd get that on the 2nd try.
So the numbers are 12, 18, and 24.
Answer: -17/15 or simplified as a mixed number -1 2/15
Step-by-step explanation: First convert both -4/5 and 1/3 to fifteenths. Multiply -4/5 by 3/3 to get -12/15. Multiply 1/3 by 5/5 to get 5/15. Then subtract 5/15 from -12/15. -12-5=-17 (numerator).
