Question

Amy collected $577$ rocks on the first day of an expedition and $183$ rocks on the second day. What is the total number of rocks that Amy collected?

• A. $740$
• B. $760$
• C. $770$
• D. $730$

Answer 1

The correct option is B $760$

Given, Amy collected $577$ rocks on the first day of her expedition and $183$ rocks on the second day.
So, the total number of rocks collected $=577+183$

Let’s represent each of these numbers based on their place value and add them.
$577$ can be decomposed as $500+70+7$.
$183$ can be decomposed as $100+80+3$.



So, Amy collected $760$ rocks in total.
