Decimals Go Math Chapter 1
line up decimal points
Dividing Decimals
Multiplying Decimals
Do not line up decimals. The decimal is
placed in the product. Find the total
decimal places in the factors. Place the
decimal point in the product so that the
product has the same number of decimal
places. (right to left)
Examples:
There cannot be a decimal in the divisor.
Move the decimal to the right to make a
whole number. Do the same to the
dividend.
Fractions Go Math Chapter 2
Converting Improper Fractions to
Mixed Numbers
Divide the numerator by the
denominator. The quotient will be the
whole number, the remainder is the
numerator, and the divisor is the
denominator.
You must have a common denominator.
Add the numerators only. Simplify if
necessary.
Converting Mixed Numbers to
Improper Fractions
Multiply the denominator by the whole
number. Then add that product to the
numerator. This sum is the new
numerator. Use the same denominator.
Subtracting Fractions
You must have a common denominator.
Subtract the numerators only. Simplify if
necessary.
Sometimes, you need to regroup in order
to subtract one fraction from another.
Multiplying Fractions
You do not need a common
denominator. Multiply across. Simplify
if necessary.
Dividing Fractions
Change the problem to multiplication.
Flip the 2nd fraction (multiply by the
reciprocal). Then multiply across and
simplify if necessary.
Converting Percents, Decimals, and Fractions Go Math Chapter 5
Percent to Decimal
Decimal to Percent
Option 1 - Take off the percent symbol
Option 1 - Move the decimal 2 places to
and move the decimal 2 places to the left. the right and place a percent sign.
Option 2 – make the decimal a fraction
over 100 and divide the numerator by
the denominator.
Percent to Fraction
Option 2 - Multiply by 100.
Write the percent as a fraction out of
100.
Divide the numerator by the
denominator.
Fraction to Percent
Fraction to Decimal
Examples:
Change the fraction to a decimal. (Divide
the numerator by the denominator.)
Then follow the rule (above) for
converting from decimal to percent.
Finding the Percent of a Number Go Math Chapter 5
Finding the Part When Given the
Whole
Finding the Whole When Given the
Part

Conversions Go Math Chapter 6
Standard conversions
Use your conversion sheet to convert
feet to yards, pounds to tons, cups to
quarts etc.
Metric Conversions
Use the metric chart. Move the decimal
left or right according to the chart.
Solving Equations Go Math Chapter 7
Isolate the variable by undoing the
addition. Do the inverse operation to
both sides of the equation.
Solving Multiplication Equations
Isolate the variable by undoing the
multiplication. Do the inverse operation
to both sides of the equation.
Solving Subtraction Equations
Isolate the variable by undoing the
subtraction. Do the inverse operation to
both sides of the equation.
Solving Multiplication Equations
Isolate the variable by undoing the
division. Do the inverse operation to
both sides of the equation.
