    Just multiply 11 by the denomenator (8) and add the numerator (3) and divide the total amount by the original denomenator (8).

    11*8=88

    88+3=91

    91/8

    multiply 8*11=88+3=91 => 91 / 8

    multiplying the denominator 8 with 11 and and the numerator 3 and keep the denominator 8 which gives the improper fraction 91/8.

    That is simple. All you have to do is take the denominator multiply it by the whole number and add the numerator. Finally place this number over the original denominator. So that would be 8x11+3 over 8 which is 91/8 as an improper fraction.

    The answer is 91/8.

    11 = 88/8 because 8 times 11 is 88.

    So, 11 3/8 = 88/8 + 3/8 = 91/8

    11 and 3/8 is (11x8)+3/8 so then you break it down to 88+3/8 then you simplify that into the improper fraction 91/8.

    And your answer is 91/8

    Multiply the denominator of the fraction (8) by the whole number (11) and then add the numerator (3).

    Display the number you calculate above as the numerator and the original denominator as the denominator.

    I'll let you do the math

    Multiply 11 by 8 then add the sum to 3.

    11*8=88

    88+3=91

    91/8

    11 x 8 = 88

    88 + 3 = 91 so, 91/8

    11 * 8 + 3

    --------------

    8

    = 91

    ----

    8

    Do you know why we do this? We do it this way because 11 3/8 is read as 11 and 3/8th. 11 is nothing but 88/8. ( Hope you know how we got this ). So 11 and 3/8 ths is nothing but 88/8 + 3/8 or ( 88 + 3 ) / 8 which is 91/8.

    [(11*8) + 3]/8 = 91/8
