Andrea rode her bike 3 2/3 miles on saturday and 4 5/6 miles on sunday.
Add together 3 2/3 and 4 5/6. The LCD is 6, so 3 2/3 should be rewritten as 3 4/6. Now 3 4/6 and 4 5/6 have the same denominator, 6.
3 4/6
+4 5/6
-----------
7 9/6. Note that 9/6 = 1 1/2, so rewrite
7 9/6 as 8 3/6, or 8 1/2.
She biked 8 1/2 miles in all.

Question: How do you solve [3.2 x (6.1 x 6.3)] - 2.8 with PEMDAS?
PEMDAS is the order of operations with which you solve an equation. So first parentheses, then exponents, then multiplication, then division, then addition, and last subtraction.
Answer: First, you solve the parentheses in the parentheses:
>6.1 x 6.3 = 38.43
Now ur equation is: (3.2 x 38.43) - 2.8
Now you solve what's inside this parentheses:
>3.2 x 38.43 = 122.976
Now you do the subtraction, because you have already solved all of what's in the parentheses:
>122.976 - 2.8 = 120. 176
And so, your answer is 120.176
This is what your equation should look like when you're solving:
>[3.2 x (6.1 x 6.3)] - 2.8 = y
>[3.2 x (38.43)] - 2.8 = y
>(3.2 x 38.43) - 2.8 = y
>122.976 - 2.8 = y
>122.976 - 2.8 = 120. 176
