Percentages as decimals. in steps explain how you get the answer 0.0001 to the maths sum 1/100%. when we put it into a calculator we are dividing 1 by 100 and getting 0.01.

0.0001 = 1 / 10000;

1/100% = ( 1 / 100) / 100 = 1/ (100*100) = 1 / 10000;

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
