Final answer:
To estimate the sum of fractions, you need to find a common denominator. In this case, the common denominator for 3/4 and 1/5 is 20. Next, convert both fractions to have the same denominator. Finally, add the two fractions together: 15/20 + 4/20 = 19/20.
Step-by-step explanation:
To estimate the sum of fractions, you need to find a common denominator. In this case, the common denominator for 3/4 and 1/5 is 20.
Next, you need to convert both fractions to have the same denominator. Multiply 3/4 by 5/5, which equals 15/20. Multiply 1/5 by 4/4, which equals 4/20.
Finally, add the two fractions together: 15/20 + 4/20 = 19/20.
