To subtract a whole number by a fraction, let's first transform the whole number into a fraction with the same denominator as the fraction to be subtracted.

Given: 4 - 9/7

Step 1: Converting 4 into a fraction with the denominator of 7.


\text{ 4 x }(7)/(7)\text{ = }(28)/(7)

Step 2: Let's now proceed with the subtraction.


\text{ 4 - }(9)/(7)\text{ }\rightarrow\text{ }(28)/(7)\text{ - }(9)/(7)\text{ }\rightarrow\text{ }\frac{28\text{ - 9}}{7}\text{ = }(19)/(7)

Step 3: Let's convert 19/7 into a mixed number.


(19)/(7)\text{ = 2 }(5)/(7)

Therefore, the answer is 19/7 or 2 5/7.
