In scientific notation, you need a number from 1 to less than 10 multiplied by a power of 10.
To turn 384,400 into a number from 1 to under 10, place a decimal point after the 3.
Now you have a number from 1 to less than 10.
3.844
Now count the number of places the decimal point moved left from its original position.
The decimal point was here: 384,400. after the last zero.
The decimal point moved 5 places to the left to be placed after the 3.
Since the decimal point moved 5 places left, the exponent of the 0 is 5.
384,400 = 3.844 * 10^5
Since 5, 4, and 2 share a factor of 2, we have to do 5*4*2/2 = 20

-1/2
(2,-5) (4,-6) =-6+5/4-2=
-1/2
Answer:
The answer to your question is 16/49
Step-by-step explanation:
Data
4/7 ÷ 1 3/4
Process
1.- Convert the mixed fractions into improper fractions
1 3/4 = (4 + 3) / 4 = 7/4
2.- Divide
4/7 ÷ 7/4 = 16/49
3.- Simplify
I think it is not possible to simplify.
4.- Also we can solve this problem by converting the division into a multiplication, just invert the second fraction.
4/7 x 4/7 = 16/49
The result is the same.
