Question

Estimate the sum or difference by rounding each number to its largest place (front-end rounding)

Answer 1

Answer:

a)

$\begin{gathered} \text{ Sum= 59,000+8,000=67,000} \\ \text{ Difference= 59,000-8,000=51,000} \end{gathered}$

Step-by-step explanation:

Rounding off 59,123 to thousands:

$\text{ As its 100th term is 1, so 59,123}\approx59,000$

Rounding off 7,854

$\text{ As its 100th term is 8, so 7,854}\approx8,000$

Therefore, the sum and difference of the given:

a)

$\begin{gathered} \text{ Sum= 59,000+8,000=67,000} \\ \text{ Difference= 59,000-8,000=51,000} \end{gathered}$
