Full Answer >To divide a whole number by a decimal number, move the decimal point to the right in both numbers until the decimal is a whole number. Then, divide the numbers normally.
Full Answer >To calculate a ratio, find the greatest common factor, or GCF, between two opposing sets of numbers and divide both numbers by the GCF. Calculate ratios up or down to find the answer to a specific ration question.
Full Answer >Subtract fractions with whole numbers by converting the mixed fractions to improper fractions, finding the lowest common denominator and subtracting the numerators. Convert the result back to mixed fractions and simplify, if necessary.
