Here are the steps to write a number between 0 and 1 in scientific notation with an example:
1. Write the number in decimal form. For example, 0.000375.
2. Count the number of decimal places in the number. In this example there are 4 decimal places.
3. Move the decimal point to the left by that number of places. This gives 3.75.
4. Write the number as a coefficient and exponent of 10. Since we moved the decimal point 4 places to the left, the exponent is -4.
So, 0.000375 written in scientific notation is 3.75 × 10-4.

Okay, let's think through this step-by-step:
* For 1 guest, you need 2 bags of spaghetti
* For 2 guests, you need 5 bags of spaghetti
* For 3 guests, you need 8 bags of spaghetti
Let's call the number of guests n. Then we can write:
For n = 1 guest, bags of spaghetti = 2
For n = 2 guests, bags of spaghetti = 5
For n = 3 guests, bags of spaghetti = 8
Looking at the pattern, it seems the number of bags increases by 3 each time the number of guests increases by 1.
So the rule is:

8:00 GED Math Week 1 Thursday
The document discusses converting fractions to decimals and decimals to fractions through division. It provides steps for changing fractions to decimals by adding a decimal and zero before dividing repeatedly, and for changing decimals to fractions by writing the decimal as the numerator over the place value of the last digit as the denominator. Examples of converting decimals to fractions are provided. Scientific notation is also covered, explaining how to express very large or small numbers as a product of a number from 1 to 10 and a power of 10.

Decimal numbers 1º eso
Decimal numbers represent quantities with fractional parts and are read as a whole number plus tenths, hundredths, etc. There are three types of decimal numbers: terminating, which have a finite number of decimal places; recurring, which repeat digits periodically; and non-recurring, which continue indefinitely without repetition. Operations on decimals involve lining up decimal points and applying the same rules as whole numbers, with the key being that the number of decimal places in the answer equals the total number of decimal places in the original numbers. Fractions can be converted to decimals by dividing the numerator by the denominator.
