    Answer:

    x = 5.75ft/2.3ft

    Step-by-Step:

    34ft/13 \frac{3}{5}   =  5.75ft/x

    34x = 13 3/5 · 5.75

    34x ÷ 34 = 78.2 ÷ 34

    34ft/13 3/5ft = 5.75ft/2.3ft

    Answer:

    2.666666666666666666666666 ( repeating decimal )

    Step-by-step explanation:

    It says a 45 foot slide casts a 30 foot shadow.

    We notice that 30 is exactly 2 / 3 of 45.

    A easier way to notice that is like 30 + (half of 30 which is 15)

    so 30 + 15 is 45 which is exactly the height of the water slide.

    The we take the 4 foot child. It is 4 foot.

    Then we do 4 times 2 / 3 which we got earlier.

    which will be 2.66666666666666666666666666666666666

    repeating decimal don’t know how to write it here
