2.8/1 times the top and bottom by 10
You get 28/10. If you divide 28 by 10, 10 goes into 28 2 times with a remainder of 8.
The 2 becomes the number and the remainder becomes the numerator whilst 10 becomes the denominator resulting in 2 and 8 tenths(8/10). Simplify the 8 tenths by dividing 2 top and bottom to get 4/5, therefore your answer is 2 and 4/5.
