estimate the given products 61 ×47. 589× 245. 9 × 677. 864 × 342
Answers
Answer:
Problem 1: 3,000
Problem 2: 147,500
Problem 3: 6,800
Problem 4: 292,400
Step-by-step explanation:
To estimate the given products and to give us easy equations that we can do in our head, I'm going to round to the nearest tens place ( you can round to whatever your teacher wants you to round to )
Problem 1:
61 ≈ 60
47 ≈ 50
60*50= 3,000
This is a close estimate because our estimate was only 133 away from the actual answer.
Problem 2:
589 ≈ 590
245 ≈ 250
590*250= 147,500
This is a close estimate because our estimate was only 3,195 away from the actual answer and with a number in the hundred thousands, it is a good estimate.
Problem 3:
9 ≈ 10
677 ≈ 680
10*680= 6,800
This is a close estimate because our estimate was only 707 away from the actual answer and with a number in the thousands, it is a good estimate.
Problem 4:
864 ≈ 860
342 ≈ 340
860*340= 292,400
This is a close estimate because our estimate was only 3,088 away from the actual answer and with a number in the hundred thousands, it is a good estimate.
