Question

Adam saved 35% of the of the 400 dollar he needs to save to buy a bike. How much money has Adam saved so far?

Answer 1

First write the relationship in words: "What number is 35% of 400?" 

Then write an equation to represent this relationship: $x = 35\% \times 400$ or, written another way $x = 0.35\times400$

And then solve:
$x=0.35\times400=140$

Then answer the question: "Adam has saved $140."
