    Answer:

    10/a=6/8

    reduce the fraction with 2

    10/a=3/4

    Simplify the equation using cross-multiplication

    40=3a

    swap the sides of the equation

    3a=40

    divide both sides of the equation by 3

    a=40/3

    Answer:

    a = \frac{40}{3}

    Step-by-step explanation:

    Given

    \frac{10}{a} = \frac{6}{8} ( cross- multiply )

    6a = 80 ( divide both sides by 6 )

    a = \frac{80}{6} = \frac{40}{3}
