<h3> The greatest number is

</h3>
<em><u>Solution:</u></em>
<em><u>Given that the numbers are:</u></em>

We have to find the number that is greatest
Convert the numbers to decimal




We can clearly see that, 199.7 is greatest number
Thus the greatest number is 
Step-by-step explanation:
hope I understand your qyestion
Equation 1 : R+G=20
Equation 2 : 7R+3G=9
Multiply Equation by 3, it becomes
3R+3G=60 ...... Equation 3
Now Equation 3 minus Equation 2
-4R = 51
R = - 51/4
Sub R into Equation 1, you can find G
15 3/4% = 15.75%
15.75% = 0.1575
The answer is A.
K = F + 459.67
Subtract K on both sides:
0 = F - K + 459.67
Subtract F on both sides:
-F = -K + 459.67
Divide each term by -1 so that the variables are positive:
F = K - 459.67
