Answer:
it depends on the work place to play it safe i would choose 12
Step-by-step explanation:
I would say it could possibly be 67
h + 2d = 6
2h + 2d = 9.60
-2h - 4d = -12
2h + 2d = 9.60
- 2d = - 2.4
d = $1.20
No, it is equal to the decimal -.3333... 1/3^-1 however, would be equal to three since the negative exponent could be brought to the top and made positive, maybe that's what you were thinking of?
1/4 + 1/2 is 3/4. the equivalent fractions would be 1/4 + 2/4 or 3/4
