Or turn it into fraction form. not sure if the answer needs tk be simplified if so 0.87 and round to the nearest 10th also if it is the problem they asked to be simplified it will be fraction form 27/31
The answer would be 46 - This is because you would do 85/10 to find the ratio. Then you would get 8.5. You would take 8.5 then divide 391 by 8.5 getting 46.
