Chapter 1.4, Problem 71E

To determine

To calculate:find the low and high estimate for $371\times 47$ .

Answer to Problem 71E

Low and high estimate for $371\times 47$ is $15000$ and $20000$ .

Explanation of Solution

Given information : consider, the expression provided in the question,

  $371\times 47$ .

Calculation : to evaluate the low and high estimate rounds off two digit number to its nearest 10^th and three digit number to its nearest hundreds.

  $400\times 50=20000$

  $300\times 50=15000$

Hence,

Thus, The Low and high estimate for $371\times 47$ is $15000$ and $20000$ .
