Oh, dude, let me break it down for you. So, if 3 over 7 equals 21 over what, we just need to do a little math dance. All you gotta do is cross multiply like it's high school algebra all over again. So, 3 times what equals 21? Well, that's just 7, my friend. Easy peasy lemon squeezy!

To solve this equation, you can set up a proportion: 3/7 = 21/x. Cross multiply to get 3x = 147. Divide by 3 on both sides to find that x = 49. Therefore, 3/7 is equal to 21/49.
