There are infinitely many possible answers. Let A be any number greater than or equal to sqrt(1547) = 39.3. Let B = 1547/A Then A*B = A*(1547)/A = 1547 So, for example, 154.7 * 10 or 1547 * 100 or 40 * 38.675
Oh, dude, like, seriously? Okay, fine. So, rounding 1547 to the nearest ten, you just gotta look at the last digit, which is 7. And since 7 is closer to 10 than 0, you round up. So, 1547 rounded to the nearest ten is 1550. Easy peasy, lemon squeezy.
