How do you convert numbers into forms?

Answer 1

See the related link about Standard Form. Standard form involves moving the decimal point so that there is only one non-zero digit to the left of the decimal point, then multiplying by an appropriate power of ten. If you moved the decimal point to the left, then the exponent of ten will be positive. If you moved the decimal point to the right, then the exponent of ten will be negative. The value of the exponent is equal to the number of places that the decimal is moved.

Example:

• 105 = 1.05 x 102 (the decimal was moved 2 places to the left)
• .00356 = 3.56 x 10-3 (the decimal was moved 3 places to the right)

Answer 2

Numbers can be converted into various forms such as decimal form, fractional form, percent form, exponential form, etc. The process of converting a number into different forms depends on the type of form you want to convert it into.

For example:

Decimal to fraction: To convert a decimal to a fraction, you can write the decimal as a division of two numbers with a denominator of 10, 100, 1000, etc. depending on the number of decimal places. Then, simplify the fraction by dividing both the numerator and denominator by their greatest common factor.

Fraction to decimal: To convert a fraction to a decimal, divide the numerator by the denominator.

Decimal to percent: To convert a decimal to a percent, multiply the decimal by 100 and add the percent symbol.

Percent to decimal: To convert a percent to a decimal, divide the percent by 100.

Scientific notation: To convert a number into scientific notation, move the decimal place to the right or left until there is only one non-zero digit to the left of the decimal point. Then, multiply the number by 10 raised to an exponent that represents the number of decimal places you moved.

It's important to note that some forms may not be appropriate for certain types of calculations or situations.
