To estimate the products of \( 79 \times 37 \) and \( 62 \times 49 \):
-
Estimate \( 79 \times 37 \):
- Round \( 79 \) to \( 80 \) and \( 37 \) to \( 40 \).
- So, \( 79 \times 37 \) is estimated as: \[ 80 \times 40 = 3200 \]
-
Estimate \( 62 \times 49 \):
- Round \( 62 \) to \( 60 \) and \( 49 \) to \( 50 \).
- So, \( 62 \times 49 \) is estimated as: \[ 60 \times 50 = 3000 \]
-
Sum of the estimates:
- Now, add the two estimates: \[ 3200 + 3000 = 6200 \]
Thus, the choice that shows the sum of the estimates is 6,200.
