Which quotient is equivalent to the mixed number
rusak2 [61]
To answer this question you will convert the mixed number into an improper fraction. To do this you have to understand that The two wholes in the mix number each equal 3/3. This would give you 6/3 for the two wholes. Add the 6/3 to the 2/3 that are there in the fraction, and you will have 8/3. the quotient(answer to a division problem) is 8/3 as a fraction.

Multiply by 5 for 5 cups (I recommend cross multiplying with fractions)
80tbsp/5cups
Multiply by 1.25
20tbsp/1.25cups
Multiply by 2.7
43.2tbsp/2.7cups
Since you can’t have .2 of a table spoon, we need to round up.
44tbsp/2.7cups

Total tbsp:80+20+44tbsp=144tbsp

We would need 144 tablespoons for 8.95 cups (9 for the same reason that we rounded up with the table spoons)
