    Answer:

    43 29/100

    Step-by-step explanation:

    Subtract 34 23/25 from 78 21/100.

    To do this, you have to turn 23/25 to something over 100.

    Multiply the numerator and denominator by 4, since that is how you get 25 to 100. This will give you 92/100. So now you have 32 92/100

    You have to take away one from 78, which makes it 77 and then add 100 to 21, since 100 is equal to 1.

    You now have 77 121/100 – 32 92/100.

    77 121/100 – 32 92/100 = 43 29/100
