172 = 0.07x divide by the 7 %
x = 2457

If B is the bigger number it means that 172 = B*7/100 (172 is 7% of the bigger number).
Which means B = 172*100/7 = 2457.14, I am surprised that this does not give a whole number....

So the bigger number, let's call it N.
You know that 7% of N is 172.
We need to write this mathematically, so you need to turn 7% into a decimal and multiply it by N.
Therefore:
.07(N)=172
Now solve for N using your calculator
N=172/.07
N= 2457.14

you have to make an equation
7/100 = 172/x
x represent the unknown number
now cross multiply
7x = 17200
divid both sides by 7
x = ~2457.14

7% means 7/100 = 0.07 times.
You have a number 172 which is 0.07 times the bigger number.
Let x = bigger number.
Then 172 = 0.07*x
=> x = 172/0.07 = 2457

x = 172/0.07 = ~2457
Technically, you should limit your answer to 3 significant figures so x = 2460
