what is the answer\
To estimate the sum of the given fractions, we can use benchmark fractions that are easier to work with.
Let's start by finding benchmark fractions for both fractions in the equation: 14/16 and 1/5.
For the first fraction, 14/16, we can think of benchmark fractions like 1/2 or 3/4. In this case, it is closer to 3/4.
For the second fraction, 1/5, benchmark fractions like 1/10 or 1/4 could be used. In this case, 1/5 is closer to 1/4.
Now let's estimate the sum of these fractions:
Using the benchmark fractions we found, we can estimate the sum of 14/16 + 1/5 as follows:
Approximating 14/16 to be close to 3/4 and 1/5 to be close to 1/4, we get:
3/4 + 1/4 = 4/4
Since 4/4 is equal to 1, the estimated sum of the given fractions is 1.
Therefore, the answer is D. 1.
