    Answer: 1 4/5 or 1.8

    Step-by-step explanation:

    Let y be the missing number

    Step 1: From the question, write out an equation

    24 – 5 × y= 15

    24- 5y = 15

    Make y the subject of formula

    -5y= 15 – 24

    -5y = -9

    Divide both sides by -5

    y = -9/-5

    = 1 4/5 or 1.8.

    Check;

    Slot in the value of y into the generated equation

    24- 5(1.8)= 15

    24-9= 15

    15 = 15

    I hope this is clear, please mark as brainliest.

    Answer:

    Step-by-step explanation:

    Let the number be x

    5 times a number = 5x

    24 – 5x = 15

    -5x = 15-24

    -5x = -9

    x= -9/-5

    x = 9/5

    x=1\frac{4}{5}

    or x = 1.8
