Question

What is the answer to 30 2/7 + 8 3/4

Answer 1

39 1/28

Explanation:

We have the following operation:

`30(2)/(7)+8(3)/(4)`

When adding mixed numbers, first we add the integer part and then the fractional part, just like this:

`\begin{gathered} 30+8=38 \\ \\ (2)/(7)+(3)/(4)=(8+21)/(28)=(29)/(28)=1(1)/(28) \\ \\ \text{ Therefore:} \\ \\ 38+1(1)/(28)=(38+1)(1)/(28)=39(1)/(28) \end{gathered}`

The result of the operation is 39 1/28
