Question

Estimate the sum or difference, by rounding each number to its largest place (front-end rounding)–36.673+39.999

Answer 1

Answer:

0

Explanation:

Given the difference:

$-36.673+39.999$

In front-end rounding, we consider the number with the largest place value.

In -36.673, the number with the largest place value is 3.

The digit after 3 us 6, so we round up as follows:

$-36.673\approx-40$

Likewise, In 39.999, the number with the largest place value is 3.

The digit after 3 us 9, so we round up as follows:

$39.999\approx40$

Therefore:

$-36.673+39.999\approx-40+40=0$

The diffrence is 0 using front-end rounding.
