Decimal Quiz 2 Review

Underline the place value to round to

Look to the number on the right of the place we are rounding to

The number on the right decides whether we are adding one to the place value being rounded or leaving it alone

everything after the place being rounded goes away

Line up the decimal points

Add zeroes as needed to make the same amount of digits

Compare whole numbers first

If whole numbers are the same, then move on to decimal numbers

Compare or order as directions describe

Read the number as though you would write it in words

The decimal number itself will be your numerator (number on top)

The last name or last decimal place value will be your denominator (number on bottom)

If there is a whole number it will go to the left side of the fraction on its own

Multiplying by positive powers of 10 means the number gets bigger and I move the decimal to the right (as many times as the exponent or zeros show)

Dividing by powers of 10 means that the number gets smaller and I move the decimal to the left (as many times as the exponent or zeros show)
