Let k be the amount of money Ken gets.

3k is how much money Susan gets.

Set up an equation: k+3k=20

4k=20

k=5

Ken gets 5 pounds, Susan gets 15.

Multiply both sides bt 28: the LCD of the three fractions, to get rid of them.

8x-14x=21x+28.

-6x=21x+28

-27x=28

x=-28/27

I accept the challenge.

$${\frac{{\mathtt{4}}}{\left({\frac{{\mathtt{30.7}}}{{\mathtt{100}}}}\right)}} = {\frac{{\mathtt{4\,000}}}{{\mathtt{307}}}} = {\mathtt{13.029\: \!315\: \!960\: \!912\: \!052\: \!1}}$$

$${\mathtt{30\,000\,000}}{\mathtt{\,\times\,}}{\mathtt{67\,000\,000}} = {\mathtt{2\,010\,000\,000\,000\,000}}$$

$${\mathtt{200\,000\,000}}{\mathtt{\,\times\,}}{\mathtt{75}}\% = {\mathtt{150\,000\,000}}$$

(4*2)+(6/3)-5=8+2-5=10-5=5.

7+(7/7)+(7*7)-7=7+1+49-7=50.

It is 50, unless you made some mistake with order of operations.

Best forum of 2015 so far.

To be more specific, what did the anons do to you?
