To estimate the sum of the fractions, 14/16 plus 1/5, we can use benchmarks.

Step 1: Find common denominators for the fractions. The least common multiple (LCM) of 16 and 5 is 80. So, let's convert the fractions to have a denominator of 80.

14/16 becomes 70/80 (multiply the numerator and denominator by 5).
1/5 becomes 16/80 (multiply the numerator and denominator by 16).

Step 2: Add the fractions together.

70/80 plus 16/80 equals (70 + 16)/80 which is equal to 86/80.

Step 3: Simplify the fraction if needed.

In this case, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD). The GCD of 86 and 80 is 2.
So, dividing both 86 and 80 by 2 gives us 43/40.

Therefore, the estimate of 14/16 plus 1/5 is 43/40.
