Answer:
D: 14 5/8
Step-by-step explanation:
Your graphing calculator may be able to handle mixed numbers directly. Even if it doesn't, you can perform the calculation as ...
(3 + 3/8)×(4 + 1/3) = 14.625
Then you have to recognize that 0.625 is more than 3/8. (It is 5/8.)
__
(3 3/8)(4 1/3) = 14 5/8
_____
Converting to improper fractions:
(3 3/8)(4 1/3)
= (27/8)(13/3)
= (27·13)/(8·3)
= (9·13)/8 . . . . . . . . cancelling a factor of 3 from 27
= 117/8 = 14 5/8
