The answer is 3.86 rounded to the hundredth place.
In the problem, the number is:
3.85663
I’ll tell you the places:
3 is the ones place. Then there’s the decimal, now we’re adding “th.” After the decimal is 8, the tenths place. After that is 5, the hundredths place. Then it’s 6, the thousandths place. Then another 6, ten thousandths place. And last, 3, the hundred thousandths place.
It’s just like the places you learned in elementary school, but backwards and with “th” added, also no “oneths place,” that just sounds weird.
And you should know how to round, but if you don’t, you simply just look at the next number after the number you’re rounding. If the number is greater than 5, round up, if less, round down. And 5 is rounded up in most cases. So here, the number after the hundredths place is 6, so we round the hundredths place up, 5 to 6.
