Why does the method of dividing fractions work?
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
What patterns do you notice when multiplying fractions of a whole number?
There is no pattern.
What is a general rule for multiplying fractions and whole numbers?
A general rule for multiplying fractions: You shall not multiply the denominator by the whole number,only the numerator.Another rule is you shall make the whole number as a fraction by putting the whole number as the numerator and 1 as the denominator before multiplying it.
How is multiplying whole number the related to multiplying fractions?
Its related to each other because in both you multiply. Whole numbers are positive integers, expect zero which is neutral (no sign). If you know the time table, this will help you to multiply fractions written as integer/integer (rational number). So you will find the right value of the product. Positive or negative value, it depends on the sign of the numbers involved in the multiplication.
How do you convert fractions with percent signs into normal fractions?
by dividing the number by 100.
Why does the method of dividing fractions work?
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
How is dividing fractions similar to multiplying fractions?
It is similar because when you divide fractions you are technically multiplying the second number's reciprocal. (Turning the fraction the other way around)
How is multiplying fractions by a whole number is different from adding adding and subtracting fractions with like denominators?
Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.
What patterns do you notice when multiplying fractions of a whole number?
There is no pattern.
What fractions are between 20 percent and 30 percent?
There an infinite number of fractions between them. 1/4 is one of them.
What is a general rule for multiplying fractions and whole numbers?
A general rule for multiplying fractions: You shall not multiply the denominator by the whole number,only the numerator.Another rule is you shall make the whole number as a fraction by putting the whole number as the numerator and 1 as the denominator before multiplying it.
Details about multiplying and dividing rational number?
Details about multiplying and dividing rational number involves modeling multiplying fractions by dividing squares to equal segments and then overlap the squares.
What multiplying factor decrease a number by 3 percent?
what multiplying factor decrease a number by 3 %
How are fractions related to math?
fractions are parts of a number

How do you decrease a number by 10 percent?
You can decrease a number by 10 percent by multiplying it by 0.9
Why is the number larger when you divide fractions?
Because it's the same as multiplying the inverse. Dividing something by one third is the same as multiplying it by three. The number will get larger.
