Question from manny, a parent: Express 22 : 5 as a decimal. Round to the nearest hundredth |
Hi Manny,
I'm going to change the problem to
Express 22 : 7 as a decimal. Round to the nearest hundredth
22:7 as a common fraction is 22/7 and to convert to a decimal fraction divide 7 into 22. I got 22/7 = 3.142857... Rounded to the nearest hundredth this is 3.14.
If you perform the same operations with 22:5 then 22/5 = 4.4 and you don't need to round.
