What is the value of 1 whole 3 by 4 as a fraction?

To convert the mixed number 1 whole 3 by 4 into a fraction, we need to follow a simple process:

1. First, recognize that a mixed number consists of a whole number and a proper fraction. In this case, we have 1 whole and 3 by 4.
2. Next, we convert the whole number (which is 1 in this case) to a fraction. A whole number can be represented as a fraction by placing it over 1, so we have 1 = 1/1.
3. Now, we need to express the proper fraction, which is 3 by 4, as a fraction with the same denominator as the whole number. Since our whole number is 1 (or 1/1), we convert it: 1 = 4/4 (because the denominator here is 4).
4. Now, we can add the two fractions together: 4/4 + 3/4 = (4 + 3)/4 = 7/4.

Thus, the value of 1 whole 3 by 4 as a fraction is 7/4.
