0.0000000009 ÷ 0.0003 = 80000/

26666666667

= 3.0×10-6

Step-by-step explanation:

Conversion a decimal number to a fraction: 9.0E-10 = 9/

10000000000

= 8/

8888888889

a) Write down the decimal 9.0E-10 divided by 1: 9.0E-10 = 9.0E-10/

1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

9.0E-10/

1

= 9.0E-9/

10

= 9.0E-8/

100

= 9.0E-7/

1000

= 9.0E-6/

10000

= 9.0E-5/

100000

= 0.0009/

1000000

= 0.009/

10000000

= 0.09/

100000000

= 0.9/

1000000000

= 9/

10000000000

Note: 9/

10000000000

is called a decimal fraction.

c) Simplify and reduce the fraction

9/

10000000000

= 9 * 1/

10000000000 * 1

= 9 * 1/

10000000000 * 1

Conversion a decimal number to a fraction: 0.0003 = 3/

10000

= 3/

10000

a) Write down the decimal 0.0003 divided by 1: 0.0003 = 0.0003/

1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

0.0003/

1

= 0.003/

10

= 0.03/

100

= 0.3/

1000

= 3/

10000

Note: 3/

10000

is called a decimal fraction.

c) Simplify and reduce the fraction

3/

10000

= 1.5 * 2/

5000 * 2

= 1.5 * 2/

5000 * 2

= 1.5/

5000

Divide: 0 / 0.0003 = 8/

8888888889

· 10000/

3

= 8 · 10000/

8888888889 · 3

= 80000/

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 3/

10000

is 10000/

3

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - eight over eight billion eight hundred eighty-eight million eight hundred eighty-eight thousand eight hundred eighty-nine divided by three over ten thousand = eighty thousand over twenty-six billion six hundred sixty-six million six hundred sixty-six thousand six hundred sixty-seven.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
