QuestionUse this result to find each sum. Estimate to check the sum is reasonable. a) $3 \frac{1}{2}+\frac{1}{5}$ b) $\frac{1}{2}+2 \frac{1}{5}$
7. For each pair of numbers, find d) $4 \frac{1}{2}+3 \frac{1}{5}$

Studdy Solution
Estimate the sum to check for reasonableness.
a) Estimate: $3.5 + 0.2 \approx 3.7$ b) Estimate: $0.5 + 2.2 \approx 2.7$ d) Estimate: $4.5 + 3.2 \approx 7.7$
Check if the calculated sums are close to the estimates: a) $3 \frac{7}{10} \approx 3.7$ (reasonable) b) $2 \frac{7}{10} \approx 2.7$ (reasonable) d) $5 \frac{1}{10} \approx 5.1$ (reasonable)
The sums are: a) $3 \frac{7}{10}$ b) $2 \frac{7}{10}$ d) $5 \frac{1}{10}$
