    91/20 = ?

    20×4 = 80

    80 + 11 = 91

    91/20 = [4×20 + 11]/20 = 4 11/20

    91/20 = [20/20 + 20/20+ 20/20 + 20/20 + 11/20] = [1+1+1+1] +[11/20] ==== 4 11/20

    The closest multiple of 20 that is smaller than and closest to 91 is 4 because 20 * 4 = 80. 5 is too big because 20 * 5 = 100, and 100 is obviously greater than 91. Now, 91 - 80 = 11, so the answer is 4 r11.

    You must have made a math error.

    5 x 20 = 100, not 90

    The correct answer is:

    4 x 20 = 80

    So there is a remainder of 11

    Answer:

    4 11/20

    Since when is 5*20 + 1 = 91?

    _____

    Last time I checked, 5*2 = 10, which means 5*20 = 100.

    4 11/20.

    hint: 20 goes into 90 only 4 times.
