    Answer:

    37.71 hours

    Step-by-step explanation:

    Saphire

    1garden/88hours

    Varsha

    1garden/ 66 hours

    Together

    1/88 + 1/66 = x

    use 264 as common denominator

    3/264 + 4/264 = 7/264

    Together they can do 7 gardens in 264 hours

    264/7 = 37.71 hours for 1 garden

    ———————————–

    Sometimes Brainly double types numbers

    If you meant 6 hours and 8 hours

    1/6 + 1/8 = x

    4/24 + 3/24 = 7/24

    24/7 = 3.43 hours
