the problem in the book is
5/8*t + 2/15*t = 17/20
5/8*t + 2/15*t = 17/20
OK, typing on here requires more parentheses than in a book where you can set up type :
5/8 = 5 / (2 * 2 * 2)
2/15 = 2 / (5*3)
17/20 = 17/2*5*2
least common denominator is 2*2*2*3 *5 = 8*15 = 120
so I multiply all terms by 120
120(5/8) t + 120(2/15) t = 120 (17/20)
75 t + 16 t = 102
91 t = 102
t = 102/91 = 1 11/91
5/8 = 5 / (2 * 2 * 2)
2/15 = 2 / (5*3)
17/20 = 17/2*5*2
least common denominator is 2*2*2*3 *5 = 8*15 = 120
so I multiply all terms by 120
120(5/8) t + 120(2/15) t = 120 (17/20)
75 t + 16 t = 102
91 t = 102
t = 102/91 = 1 11/91
how do u check it?
