Question

the largest river in the world is the Nile, which is 4,145 miles long. It us 138 miles longer than the second largest river, which is the Amazon in South America. How long is the Amazon river?

Answer 1

The Nile = 4,145

 

The Amazon is what?

 

Tha Amazon is not as long as the Nile and is 138 miles less than the Nile so you need to subtract what you do know.

 

The length of the Nile (4,145 ) take away 138 miles will tell you how long the Amazon is

 

4,145-138=4,007

 

or the Amazon PLUS 138 will be the same as the Nile
