Find 98% of 18. Round to the nearest tenth if necessary.

Answer 1

To find a given percentage of a given number, we can transform the percentage into decimal and multiply it by the number.

So, 98% can be written in the decimal form by deviding it by 100%:

`98\%=(98\%)/(100\%)=0.98`

Since they are equivalente, we can now multiply it by 18:

`0.98\cdot18=17.64\approx17.6`

Thus, 98% of 18 is approximately 17.6.
