$70,000,000

Okay Sandra Bullock received seventy million dollars which is 15% of the movie Gravity's gross income. So how much did the movie Gravity "presently"  make ?

Let's see, first we change 15% to .15

.15 of  ?=70,000,000 (15% of what equals 70,000,000)

 We divide both sides by  .15

(.15)/(.15) of ?= 70,000,000 / (.15)
      ?=466,666,666.67

answer: 466,666,666.67 of course with Gravity making about  467 million dollars nobody is going to worry about the extra 67 cents.

We can also use 15/100 rather than .15

15/100 of ? =70,000,000

Now we invert (15/100) to (100/15) and use that to multiply on both ends.

(15/100)  x (100/15) of ? =70,000,000 x (100/15) 

Of couse (15/100) X(100/15)=1 (one)

                ?=70,000,000 x (100/15) (First we multiply 70,000,000 by 100 which gives us 7,000,000,000 (7 billion) then divide that result by 15 .
            ? =466.666,666.67
Yep, the same answer so the movie Gravity gross about 467 million.

 Now let's check by multiplying 466,666,666.67 by 15 %

                  466,666,666.67 x .15

               answer=70,000,000.0005
So, Sandra Bullock got paid 70 million dollars and 1/2000 of a cent  Click here for more about Sandra Bullock
