How do you solve 42 divided by 63
Dafna1 [17]

42  ÷ 63

  63 -> 420

63x6=378


420-378=42

       63->420


So, how many times does 63 go into 42? Well, it doesn't. So put down a zero on your paper, and then a decimal. So if we add a zero onto 42, it becomes 420. Well, 420 is divisible by 63. In fact, 63 goes into 420 6 times, making a total of 378. 420-378 = 42. Then the process begins again. So you've got a 0.6, and that six just keeps on repeating. On paper, you're gonna wanna put a dash over the six to show that it's repeating.


Anyways, the answer is .66 repeating.
