Question 256058
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)
