Question

solve the problem 100+20+400-45​

Answer 1

Answer:

The strategy here is to see how many times the "percent number" (in this case, 25) goes into 100, and then count by that number until we reach 100-the whole thing. Here, we're told that 25% of a number is 5. So, to find 100% of the number, we count by 25s up to 100: 25, 50, 75, 100. 100% is 20.

Answer 2

Answer:

100 + 20 + 400 - 45 = 475
