Question

What is this in standard form

Answer 1

Hello!

As you can see each number will switch the zeros on the number to a certain place value. Our first number is in the ten billions. The second is in the billions. We will add the number in the billions spot into the ten billion, giving us 12 billion.

We will go on with this as as follows.

12,000,000,000
+   100,000,000 (hundred millions)
---------------------
12,100,000,000

As you can see, the next number is in the hundred thousands, so we will have the ten millions and millions be zeros.

12,100,000,000
+           500,000
-----------------------
12,100,500,000
+             60,000
-------------------------
12,100,560,000
+               2,000
-------------------------
12,100,562,000.000
+                          .008 (eight thousandths)
---------------------------------------
12,100,562,000.008

I hope this helps!
