The question type is the same as the previous question which means the process to find the answer is the same except the numbers have changed.

princeevee · Answer

4/10 is the fraction, a.k.a its 2 x 2 /10

princeevee · Answer

2/5?

Hero · Answer

Show all of your work please. How did you come up with 4/10 to begin with?

princeevee · Answer

well, 2 dimes and nickles out of all the coins, which is 10, its really simple that i dont need to actually explain

Hero · Answer

The answer is correct. You executed nearly flawlessly but you posted something erroneous. You must add the fractions 2/10 + 2/10 = (2 + 2)/10 = 4/10 = 2/5
