Explain why scientific notation is helpful when computing with large numbers.

Answers And Explanations:

Question 1.

Pulling out like terms :

1.1     Pull out like factors :

  12y - 10  =   2 • (6y - 5)  

Equation at the end of step  1  :

  Divide both sides by  2  

 Divide both sides by  6  

 y-(5/6)  > 0

Add  5/6  to both sides

y > 5/6.

Therefore, y = 5/6

Question 2.

To make fractions improper with whole numbers, you must multiply the Denominator by the whole number, then add the Numerator to the Product.

First we multiply 32 by 5.

32 x 5 = 160.

Then we add the Numerator which is 1.

160 + 1 = 161, then we put it over the Denominator, your final answer is 161/5.

Therefore, 161/5 is your final answer.
