7÷3×5x÷12. Can someone help me multiply rational expressions and divide rational expressions? Please and thank you.



Answer :

In this case, because there are no exponents or brackets, (BEDMAS) you would just do it in the order given. 

7÷3×5x÷12= 7×1/3 × 5x × 1/12
To divide, make the numbers after the divide sign into fractions.(ex: 3= 1/3)
Then multiply it out:
                = 7/3 × 5x/12
                = 35x/34
Then because the numerator is bigger then the denominator, make the improper
fraction into a mixed fraction:
                = 1 1x/34

Hope this helps!
