42 = 0.21428571428571427
n=9. Because n+42=51. Subtract 42 from both sides and n=9
The GCF is 3.
5 5+4 = 9 52+42 = 41

Not evenly.
No it cannot. 42/4= 10 with a remainder of 2

42/9 is much greater. 42/9 is the same as 4 and 7/9 (since 9 goes into 42 4 times with 7 left over). Since 5/9 is less than 1, clearly 42/9 is much greater. 7/9 alone would still be greater than 5/9. But since it's not just 7/9, but 4 and 7/9, it is obviously greater than 5/9.
378 divided by 9 = 42
42 ÷ 9 = 4 with remainder 6 or 4.6667
Six (7x6=42)
9% of 42= 9% * 42= 0.09 * 42= 3.78
