Step-by-step explanation:
Add the two parts of the ratio together
2 + 5 = 7
Find 5:7
5:7 = x:420
5/7 = x/420 Cross multiply
7x = 5 * 420 Combine the right
7x = 2100 Divide by 7
x = 2100/7
x = 300
Find the second number
420 - 300 = 120
120 : 300 is the answer
Divide top and bottom by 60
120/60 = 2
300 / 60 = 5
