The perfect cookie… is it thin and chewy or thick and cakey? Whichever, knowing how to manipulate the ingredients is the key. It’s all about the % of moisture content: a wetter cookie dough spreads thin during baking. A thin and flat cookie will lose most of its water during baking, creating a denser chewier cookie with low moisture%.

 

For thick soft cookies, decrease the dough's moisture content by adding extra flour, using cold butter, white sugar instead of brown, whole eggs not just the yolk and baking powder. After baking this cookie will have a higher moisture %.

Changing a decimal to a percent is done in 2 steps, based on the idea of multiplication by 100. Multiplication by 100 is the same as moving the decimal point two digits to the right.

0.20 = ? %

  1. Move the decimal point two places to the right
  2. Remove the % symbol

Percents can be greater than 100%. Since 1 = 1.00 = 100%, we would expect 1.5 to be greater than 100%. In fact, 1.5 = 150%.

A Short Review

Examples:
0.41 = 41%
  1. Moving the decimal point 2 spots to the right results in 41.00000..., which is just written as 41, no need for trailing zeros.
  2. Write the % sign after the 41
0.0025 = 0.25%
  1. Moving the decimal point 2 spots to the right results in 000.25, which is just written as 0.25, no need for leading zeros.
  2. Write the % sign after the 0.25

Task: Convert 0.6 to percent.

Another way to get the answer, solving as an equation: episode 5 1

  1. First off, recognize that a decimal can be written as a percent. Decimals are related to percents, they can be converted back-and-forth. In this approach, 0.6 is converted to percent through an equation.

    Now 0.6 is one side of an equation. episone 5 2On the other side is a division by 100. This 100 comes from the fact that percents always have an invisible “divided by 100” concept with them. The % sign is actually short for “out of or divided into 100”.

    The unknown amount can be represented by the letter x.  Algebra is used to calculate x.  After multiplying both sides of the equation with 100, we get a value for x:

  2. Set up the problem: 100 ∙ decimal = x
  3. Calculate  100 ∙  0.6 = 60
  4. Take a pencil and write down  “x = 60”
  5. Write the % sign after the 60 Now you`re done with the math.
  6. The last step: check your work, make sure everything was copied and written correctly then determine that the correct way to write the answer is 60%

0.6 = 60%
