You can put this solution on YOUR website! "The ratio of spiders to flies is 15 to 13. If there are 3556 in all, how many of them are flies?"
15 spiders to 13 flies, means:
13 flies to 28 total
Set up a proportion:
13 flies / 28 total = x flies / 3556 total
28x = 13(3556) {cross-multiplied}
28x = 46,228 {multiplied 13 by 3556}
x = 1,651 {divided both sides by 28}
1,651 are flies
