3/5 + 3/4 round each fraction and estimate the sum. add the two fraction using a common denominator and then round the result. which estimate is closer to the actual answer.
Both round up to 1 each.
Multiply numerator and denominator of 3/5 by 4 and 3/4 by 5, then add.
Compare both sums.

consider the sum of 3/5 + 3/4. Round each fraction and estimate the sum. Add the two fractions using a common denominator and then round the result. Which estimate is closer to the actual answer?
This is stupid

To add the fractions 3/5 and 3/4, we need to find a common denominator. In this case, the least common multiple (LCM) of 5 and 4 is 20. We can convert both fractions to have a denominator of 20.
To convert 3/5 to a fraction with a denominator of 20, we multiply both the numerator and denominator by 4:
(3/5) * (4/4) = 12/20
To convert 3/4 to a fraction with a denominator of 20, we multiply both the numerator and denominator by 5:
(3/4) * (5/5) = 15/20
Now, we add the fractions:
12/20 + 15/20 = 27/20
To round this fraction, we can divide the numerator by the denominator:
27 ÷ 20 ≈ 1.35
Now let's estimate the sum using rounded fractions.
For the fraction 3/5, we round down to the nearest whole number because the numerator is less than half the denominator. So, 3/5 ≈ 0.
For the fraction 3/4, we round up to the nearest whole number because the numerator is greater than or equal to half the denominator. So, 3/4 ≈ 1.
Adding the two rounded fractions:
0 + 1 = 1
Comparing this estimate to the actual sum of 1.35, we can see that the estimate of 1 is closer to the actual answer than rounding the individual fractions.
