Answer:
21
Step-by-step explanation:
converting mixed numbers to fractions, our initial equation becomes,
7
3
×
9
1
7/3×9/1
Applying the fractions formula for multiplication,
=7/3 x 9/1
=63/3
Simplifying 63/3, the answer is
=21
2 1/3 * (6+3)= 21
(6+3)=9
So now it is 2 1/3 * 9
9 × 2*3+1/3= 7/3
9/1 ×7/3= 21
