It calculated itself for you, my friend, but if you need a response, it is: $${\frac{{\mathtt{6\,456}}}{{\mathtt{699}}}} = {\frac{{\mathtt{2\,152}}}{{\mathtt{233}}}} = {\mathtt{9.236\: \!051\: \!502\: \!145\: \!922\: \!7}}$$
It's Morphing Time!
Using PEMDAS, solve for parentheses first, in this case being -5+9. You will get 4. Next, multiple 40 by 4 to get 160. Finally divide -800 by 160 to get the solution of -5.

To explain the answer, divide 100 by 50 to get 2. Multiply the numerator and denominator by 2 to get 66/100. A percentage is a number out of 100 thus giving you 66%.
A jiffy is 1/60th of a second, multiply that by 60. You get 60, there are 60 seconds in a minute, 60*60 = 3600 jiffies!
First, distribute the 4 to the n and t. This will give you the new equation of
3n + 5t - 4n + 4t + 7
Next, combine the like terms
(3n - 4n) + (5t +4t) + 7
Your new equation is:
-n + 9t + 7
Find a common factor for the numerator and denominator. In this case it is 2. -4/2 = -2 and 6/2 = 3 Put the numbers together in the fraction again and you get (-2/3) or .66667 (the 6 is infinite, so your teacher might prefer just 0.67)
That would be (64/3)/(4/3) They share the same denominator, so just divide 64 by 4 to get 16. Your answer is 16. Hope this helps!
