When working with mixed numbers, it is usually easier to convert them to improper fractions, do the operations, and then to convert any resulting improper fraction back to a mixed number:
4/5 × 1 2/3 = 4/5 × (1×3+2)/3
= 4/5 × 5/3
= 20/15
= 4/3
= (1×3+1)/3
= 1⅓
((3 over 4) multiplied by 2) over 3 = 0.5
1/2*3= 3/2 = 1.5
16 2/3 = 50/3, multiplied by 1/3 = 50/9 which is 5 and 5/9.
2/15
8.16667
39/6 or 6 and 1/2
2/21
-6
2/3 multiplied by 9/1
3/2 x 4/8= 6/8
3/5 x 1/2 = (3 x 1)/(5 x 2) = 3/10 or 0.3
