Answer:
Explanation:
To estimate the sum of 56.7 and 23.44 using the front-end method, you can round each number to the nearest whole number and then add them together. This will give you an estimate of the sum that is close to the actual result.
Using this method, you would round 56.7 to 57 and 23.44 to 23, and then add them together to get an estimate of 80. This is a reasonable estimate of the sum of 56.7 and 23.44, which is actually 80.14.
Note that this method is not as accurate as using a calculator or performing the exact calculation, but it can be a useful tool for quickly estimating the sum of two numbers.
