Plz be a long answer

Answer 1

43 29/100

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
