So to answer this. lets find the value of 9/15

9/15

Now we know the value of the fraction is 0.6. Now we need to find th4e value of x that makes 15/x=0.6

To find the answer for this, just divide 15 by 0.6:

Hope this helps! ;)

Which statements represent the rules of significant figures? Check all that apply.
maksim [4K]

Answer:

The integers 1, 2, 3, 4, 5, 6, 7, 8, and 9 are always significant.

Zeros in between numbers are always significant.

Step-by-step explanation:

There are three rules by which the number of significant figures can be determined:

  • The digits which are other than the zero are said to be significant figures.
  • Any zero which is present between two significant figure is said to be significant.
  • The zero which appears in the right of the decimal portion in the end is significant. The zero which comes after the decimal is not significant.
