When doing fractions why is it easier to multiply and divide fractions than add and substract fractions?
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).
What else can I help you with?
Why is multiply and divide fractions is important?
because it is easier than adding and subtracting so many times??
Do you need common denominators when subtracting fractions?
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.
How do you multiply decimals with fractions?
Change the decimal into a fraction or the easier way is to turn the fration into a decimal, then multiply.
Why do you flip fractions?
So its easier to add subtract or most commonly multiply
Why do you switch the numbers around when dividing fractions?
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

Why is it that we don't divide on a dividing fraction?
It's easier to multiply the reciprocal.
Why is it that when solving a dividing fractions problem no actual dividing happens?
It's easier to multiply the reciprocal.

What number could you use to divide by seven?
You could multiply by 0.142857 with the underlined string repeating. However, it is easier to divide by 7.
How do you work out 2 percent of something?
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.
Is fractions easier or decimal?
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.
Why convert mix number to improper fraction when multiplying mix number?
It's much easier to multiply fractions than it is to multiply mixed numbers. Try either one some time.
What is 3 and 2 eights times 6 and four sevenths?
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
