Here is the problem:
%284+and+%281%2F5%29%29+%2A+%283%2F4%29+%2A+6
step 1 - turn mixed number into improper fraction and we get
%2821%2F5%29+%2A+%283%2F4%29+%2A+%286%2F1%29
step 2 - multiply the top and bottom to get
378%2F20
step 3 - reduce to get
189%2F10
or
18 and 9/10

4 1/5 x 3/4 x 6 = ?
4 = 4/1 = 20/5 (multiply top and bottom by 5, 5/5=1)
6 = 6/1
21/5 * 3/4 x 6/1
(21*3*6)/(5*4*1) (multiply tops and bottoms by each other)
(63*6)/20
378/20 (now simplify the answer)
189/10 (divided top and bottom by 2)
180/10 + 9/10
18 + 9/10
18.9 (the answer)
