What is a good estimate for 380% of 60

I would multiply 60 by 3, since its 300+%

60 x 3 = 180

From there I would then add at least half of 60, which is 30

180 + 30 = 210

Since it is 380, I would just add another 20 to the equation to get around:

210 + 20 = 230

This should be a good enough estimate that is close to 380% of 60

I would personally write it as a proportion:

x/60=380/100

100x=22800

22800 divided by 100=228

380% of 60 is 228
