    Answer:

    The business started with 23/24 of their tank full

    Step-by-step explanation:

    Step 1.

    Find the LCM of the denominators (2,6 and 8)

    =24

    Step 2.

    Change all the fractions to have a denominator of 24

    1/6=4/24

    1/8=3/24

    1/2=12/24

    3/4= 18/24

    Step 3.

    Work backwards

    18/24-12/24

    =6/24+3/24

    =9/24+(2×4/24)

    =17/24+6/24

    =23/24
