Answer:

19/20

Step-by-step explanation:

1 3/4 is an mixed number. Multiply the mixed number by the denominator then add it to the nominator. This would give you 7/4. Now you have to find a common denominator for both the fractions. This would be 20 for both. Multiply 7/4 by 5 to get the denominator to 20, and the 4/5 by 4. This leaves you with 35/20 - 16/20. Then subtract.
Solve 1 and 3/4 - 4/5
= 7/4 - 4/5
= Common denominator of 4 and 5 is 20
= 35/20 - 16/20
= 9/20
So, in conclusion, the answer to this question is; 9/20
