Question

7.8 X 103--------------1.2 X 104​

Answer 1

;-;

Let's just do a bunch of math below.

7.8 X 103          ?

-------------- =    ------

1.2 X 104           ?

So, first, we're gonna do 7.8 multiplied by 103 to get 803.4.

Thus....

7.8 X 103         803.4

--------------   =  -----------

1.2 X 104              ?

Then we would do 1.2 multipied with 104 to get a product of 124.8.

Therefore....

7.8 X 103         803.4

--------------   =  -----------

1.2 X 104           124.8

Dividing 803.4 by 124.8 would get you a quotient of 6.4375.

Your answer is 6.3475.~

Have a nice day~
