What is 1 7/8 • 5/6<br> And 2 1/3 • 5/16
m_a_m_a [10]

Answer:

55/24

Step-by-step explanation:

First, multiply 1 7/8 by 5/6, obtaining 15/8 times 5/6, or 75/48.

Next, multiply 2 1/3 by 5/16.  This is equivalent to multiplying 7/3 by 5/16, and the result of this multiplication is 35/48.

Now combine 75/48 and 35/48, obtaining 110/48, or 55/24.
