The three answers you have are correct. The last fourth answer is coincidentally "angle 4". If another number other than '4' was in the diagram, then you would label it as angle X (replace X with that number in question).
note: you can say "angle 4" or you can use the angle markers as you have been doing. It's probably best to stay consistent.
By rounding each number to the nearest whole number is 23.5
Given,
Estimate 38¼ - 14¾
and, by rounding each number to the nearest whole number.
Now, The solution is :
=38¼ - 14¾ = 153/4 - 59/4
=> 
=> 94/4
=> 23.5
Estimation a number to the nearest whole number:
To round a number to the nearest whole number, you have to look at the first digit after the decimal point. If the digit is less than 5 (1, 2 , 3, 4) we don't have to do anything, but if the digit is 5 or greater (5,6,7,8,9) we must round up.
Hence, By rounding each number to the nearest whole number is 23.5
