First, add up the parts of the ratio... 2+3+5=10 then divide the whole into individual parts... 25/10=2.5 then multiply the value of 1 part by the amount in the ratio... 2.5 x 2 =5 2.5 x 3 = 7.5 2.5 x 5 = 12.5 so the final ratio is 5kg:7.5kg:12.5kg Hope this helps :)
{2, 5, 3, 1, 0, 3, 7, 2, 2} is the data set. We can find this by finding <span>relative frequency of 3 = 2/9 = 0.22 and then 150 times .22 = 33 units</span>
