In the given question, there are several information's of immense importance and they can be used to find the necessary answers. It is already given that John and Andrew have 3.40 pound together. It is also given that John has 1.20 pound more than Andrew. It is also assumed that John has"u" pound and Andrew has "v" pounds. Then we can write the two equations as u + v = 3.40 u = v + 1.20 To find the values of u and v, we can replace the u in the first equation with the value of u in the second equation. Then u + v = 3.40 (v + 1.20) + v = 3.40 2v + 1.20 = 3.40 2v = 3.40 - 1.20 2v = 2.2 v = 2.2/2 = 1.1 Now we replace the value of v in the first equation to find the value of u. u + v = 3.40 u + 1.1 = 3.40 u = 3.40 - 1.1 u = 2.3
7/25 because he was on the treadmill for 28% of his workout and when you turn that into a fraction you get 28/100. Lastly, you simplify by dividing both numbers by the greatest common factor which in this case is 4.
