Find the least common denominator for these two rational expressions -7/x -5/6x^2

Least Common Denominator is 6

Step-by-step explanation:

In this question we simply find the factors of the denominators first.

Fractions are (-7)/x and (-5)/6

Denominators are x and 6

Factors of first denominator = x×x

Factors of second denominator = 2×3×x×x

Common factors are x×x

So LCM of these two denominators will be = 2×3×common factors of both

                                                                       = 2×3×

                                                                       = 6

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
