If a number has to be put into standard form from the written, is that in decimals or fractions?

decimals.

When a number needs to be put into standard form from written form, it typically refers to writing the number in decimal form. Standard form, also known as scientific notation, is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It consists of a number between 1 and 10, multiplied by a power of 10.

To convert a number into standard form, you follow these steps:

1. Identify the digits before the decimal point in the written form. These will be the digits of the number greater than or equal to 1.

2. Count the number of decimal places from the first digit after the decimal point to the end. This will determine the power of 10.

3. Combine the digits identified in step 1 with the decimal places from step 2.

For example, if the written form is "0.000025", to convert it to standard form, you would:

1. Identify the digits before the decimal point, which in this case is 25.

2. Count the number of decimal places, which is 5 (from the first digit after the decimal point to the end).

3. Combine the identified digits and decimal places: 25.000025.

In standard form, this would be written as 2.5000025 x 10^-5.
