441 is odd, so we can't divide it by 2.
Since the sum of its digits is 
, which is divisible by 3, we can divide 441 by 3, and we have
Which is still divisible by 3, because 
. We have
49 is not divisible by 3 anymore, nor by 5 (it doesn't end with 0 or 5).
It is divisible by 7 though, we have
and finally,
So, the factorization of 441 is
Answer:
0.5:1
Step-by-step explanation:
laps:minutes
So we can find how much Ronald runs in 2 minutes, by dividing 6:12 (or 6/12) by 6. This will give you 1:2 (One lap = 2 minutes).
But you're looking for 1 minute, so with 1:2, you have to divide them by 1/2, so it will be 0.5:1.
The equation of this line in slope intercept form is y= 3/7x
