Question

my brother has a collection of 570 stamps.two thirds of this stamps are from europe how many are europian stamps​

Answer 1

Answer:

380 stamps

Step-by-step explanation:

Total no of stamps=570

Let us assign a variable x for the no of stamps from Europe

Fraction of stamps from Europe=(2/3)rd of 570

x=(2/3)*570=2*190=380 stamps.

It is ur choice whether u want to assign a variable or not.But assigning variables will be very useful for large word problems that you will face in higher classes.
