Answer:

1/3×2/4= 3/12 or 1/4

5/6×2/3= 10/18 or 5/9

4×8/9= 32/9

(whole numbers like 4 has always an invisible denominator 1 that is why the fraction of 4 is 4/1)

2/3×6= 12/3 or 4/1 or 4

2/5×2 1/3= 2/5×7/3= 14/15

(when multiplying with a mixed numbers, you must change the mixed number into an improper fraction first. wherein, 3×2+1)

1/4×3 2/3= 1/4×11/3= 11/12

3 1/4× 5= 13/4×5/1= 65/4

6×7 1/2= 6/1×15/2= 90/2 or 45/1 or 45

3 1/3×2 1/4= 6 1/12

(in multiplying of both mixed numbers, you can just multiply the whole number to whole number, to numerator to numerator and denominator to denominator.)

1 3/8×1 1/2= 1 3/16

hope this will help
