Hello there! The answer you are looking for is - 3/4! (or 0.75% if you need a decimal.)
To Solve this it is quite simple, First convert the percentages to decimals.
1 3/4 -> 1.75
2 2/3 -> 2.50
Then after that, just line it up as a normal subtraction problem (larger number up top)
2.50
- 1.75
Which is equal to -> 0.75.
After that, just convert it back to a percentage if needed. :)
Have a Great Day & Perhaps Brainliest? :)
