Question 1200194
<font color=black size=3>
Answer: <font color=red size=4>2%</font>



Reason:
The jump from "1 billion" to "1 trillion" is "times 1000"


1 billion = 1,000,000,000 = 1 with 9 zeros
1 trillion = 1,000,000,000,000 = 1 with 12 zeros
The extra 3 zeros is from the "times 1000".


Or you can use scientific notation which is probably the better way to go. 
This avoids the tedious busy-work of writing all those pesky zeros.
1 billion = 1*10^9
1 trillion = 1*10^12
Notice how the exponents subtract to 12-9 = 3, showing a ratio of 10^3 = 1000


I'm bringing this up because we can convert "3.4 trillion" into an equivalent format using "billion" as the unit.


1 trillion = 1000 billion
3.4*1 trillion = 3.4*1000 billion
3.4 trillion = 3400 billion


Then we divide the amount cut (68 billion) over the original budget (3400 billion). The units "billion" cancel out.


(68 billion)/(3400 billion) = 68/3400 = 0.02
Move the decimal spot over two spots to the right to get to the final answer of <font color=red>2%</font>
