8 17/18 because if you change 3 and 5/6 to an improper fraction it is 23/6 and if you change 2 and 1/3 to an improper fraction it’s 7/3. And if you multiply those two numbers you should get 161/18.and 18 can go into 161 8 times with a remainder of 17 which makes 8 the whole number and 17/18 the fraction.so 3 and 5/6 times 2 1/3 = 8 17/8
You can do without the mixed numbers then when you have your answers in the without mixed numbers, you get them mixed numbers and plus them together that's it😂
you sure this is right bc when you divide 10 by 143 you would get no remainder bc you should just at one more 0 at the end then subtract so you get no remainder
