Question

(Will give brainliest with first correct answer) What is 3 3/8⋅4 1/3 ? (Fractions with mixed numbers)

Answer 1

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
