Question

Add. 1 1/2 + 3/5 + 1/8 A. 1 5/13 B. 27/15 C. 2 9/40 D. 1 3/8

Answer 1

Get the mixed number into one fraction
$\frac{3}{2} + \frac{3}{5} + \frac{1}{8}$
Get a common denominator
$\frac{60}{40} + \frac{24}{40} + \frac{5}{40}$
Now add
$\frac{89}{40}$
You can get it back to a mixed number
$2 \frac{9}{40}$

Answer 2

Hello! And thank you for your question!

First we are going to find the LCD:

LCD = 40

Then we are going to make the denominators the same as the LCD and change the numberators:

1 + 20/40 + 24/40 + 5/40

After that we will combine the denominators:

1 + 20 + 24 + 5 over 40.

Then Simplify the numberators:

1 + 49/40

Next change 49/40 into a mixed fraction:

1 + 1 9/40

Then simplify further:

2 9/40

Final Answer:

2 9/40
