Eighty per cent of tsunamis occur in the Pacific Ocean. Represent the percentage of tsunamis that did not ocur in the Pacific Ocean as a decimal (correct to 3 decimal places)?

Thanks, Chhoeuk

If 80% of tsunamis occur in the Pacific, then 20% of them did not occur in the Pacific.

Remember, percent is just a fancy word for "out of 100" or "divided by 100"

so 20% = 20/100 = 2/10 = 0.200 to three decimal places
