Hey there!

\frac{7*3}{4} =n

Simplify the numerator  (the top part))

7*3 = 21

Then, simplify the denominator (the bottom part, let's pretend it is multiplied by a(n) invisible 1 ))

4(1) = 4

Our answer is: \boxed {n=\frac{21}{4} }

Answer:

um.

Step-by-step explanation:

So he is asking, abstractly, from lack of context, if his house is close enough to the bank?

This makes little sense, abstractly. I mean, does he live in a post-apocalyptic Mad Max setting where he needs explosives and men or perhaps a frozen-over world where he needs large steam-powered engines to drill through the permafrost? It makes little substantiated sense.

So you need to know how much money he has, his charisma level, and the setting of the plot.

If the property is next to the bank, then it would be, by far, close enough to the bank.

Whenever you have __% more of something and want to find the new value, first convert the percent to a decimal. Then multiply the original value by (1.00+that decimal). 

You have 6480 kg of sugar. 75%=0.75. If you want 75% more sugar, you would want 6480*(1.00+0.75) = 6480*(1.75) = 11,340 kg of sugar.
