Divide 270 in the ratio 3:2:1
As you can see from the question there are 6 parts that 270 needs to be divided by. One sixth of 270 is equal to 45 and so one of the parts is equal to 45. To get the ratio, you have to simply multiply the amount of parts needed by 45. So 3 x 45=135 and 2x45=90. This will give you the ratio needed : 135:90:45. To check this is correct, you can add the values up to make sure it totals to 270.
