It is easier to multiply or divide fractions than to add or subtract fractions because in multiplication, you just have to multiply the numerator by the numerator and the denominator by the denominator. Same applies with division of fractions, except that you have to reciprocate the fraction you're dividing with (divisor) then proceed to multiplication.
Whereas, in addition and subtraction of fractions, you still have to get their Least Common Denominator (LCD).
because it is easier than adding and subtracting so many times??
Change the decimal into a fraction or the easier way is to turn the fration into a decimal, then multiply.
probably to multiply easier
So its easier to add subtract or most commonly multiply
Yes. You need common denominators if you want to:Add fractionsSubtract fractionsCompare fractions ("which is larger?")You do not need common denominators to multiply or divide fractions. Thus, in the case of fractions, multiplication and division is actually easier than addition and subtraction.
It's easier to multiply the reciprocal.
It's easier to multiply the reciprocal.
You could multiply by 0.142857 with the underlined string repeating. However, it is easier to divide by 7.
Some people find rational fractions easier, others prefer decimals fractions. For some purposes rational fractions are simpler, for others decimals are easier. So there is no simple answer.
2% of something means 2/100ths of it. Divide by 100 and then multiply by 2. You can also multiply by 2 then divide by 100, or even divide by 50, if that's easier, because 2/100 = 1/50.
you switch the second fraction around ( multiply by the reciprocal ) because it is way easier than trying to actually divide the fraction by dividing, you get the same answer. but we multiply by the recipricol because multiplying fractions is simpler. example.... 4/6 divided by 8/5 you then get 4/6 * 5/8 = 5/12
It's much easier to multiply fractions than it is to multiply mixed numbers. Try either one some time.
Because it keeps you from having to divide, multiply, and subtract
The way to determine it is to divide 13 by 50 and then multiply by 100. In this case it is easier to multiply both by 2 and it gives you 26 over 100, which is 26 percent.
Some people think it is easier to multiply and divide by powers of ten than by 3, 12 or 36.
That is because - for example - some calculations are easier in polar coordinates, and some are easier in rectangular coordinates. For example, complex numbers are easier to add and subtract in rectangular coordinates, and easier to multiply and divide in polar coordinates.
The difference is that they equivalent fractions worksheets have graphics and explain the concepts in easier to understand language. I find them to be an easier and fun way to introduce and explain fractions.
this is simple. for the multiplication of fractions, you multiply both the Numerator and denominator straight across. first change the mixed numbers to improper fractions 3 2/8---- 26/8 6 4/7---- 46/7 multiply them to get... whatever... and simplify it. if your teacher wants it in mixed number form then do so but it is easier to keep fractions as improper fractions for this reason
To find a volume you usually need to multiply values together. When working with mixed numbers it is usually easier to convert them into improper fractions, do the calculations and convert any resulting improper fraction into a mixed number. So you don't need to use either format, it's just that improper fractions are easier to manipulate.
Because it is much easier to do further calculations when you have smaller fractions.
Accountants typically convert fractions to decimals. They do this by dividing the fractions and getting a decimal number. Decimals are easier to work with in accounting.
yes, but it is a lot easier if you keep it in fractions (easier to graph) mind you, standard form doesn't allow fractions.
Percentages are easier for some purposes, harder for other.
To multiply two fractions, the numerator (top part) of the result is the product of the numerators, and the denominator (bottom part) of the result is the product of the denominators. There is no need to convert to a common denominator first; this is only necessary to add, subtract, or compare fractions. For example, 1/2 x 5/7 = (1x5) / (2x7) = 5/14. Note that it is easier to do any simplifications BEFORE doing the actual multiplication.
Well, if you divide a pizza, you get a fraction of the pizza. This makes fractions easier to understand. or the peices you cut and take away one that is a fraction so an example is i have a pizza its cut into 7 pieces so i take away one i have 6/1
