Find the least common denominator of 7/20 and 3/28

Mathematics
1 answer:
Genrish500 [490]3 years ago
7 0

Answer:

140

Step-by-step explanation:

We have been given two fractions \frac{7}{20} and \frac{3}{28}. We are asked to find the least common denominator of both fractions.

To find the least common denominator of both fractions, we will find least common multiple of 20 and 28.

Prime factorization of 20: 2\times 2\times 5

Prime factorization of 28: 2\times 2\times 7

Least common multiple of 20 and 28 would be: 2\times 2\times 7\times 5=140.

Therefore, the least common denominator of both fractions would be 140.

the polynomial 3x+5 is divided by x+2 what is the quotient, pls be quick im taking a algebra progress check due in 25 min
il63 [147K]

Answer:

The quotient of the rational function is 3 -\frac{1}{x+2}.

Step-by-step explanation:

We proceed to solve the expression by solely algebraic means below:

1) \frac{3\cdot x + 5}{x+2} Given

2) \frac{(3\cdot x + 5) + 0}{x + 2} Modulative property

3) \frac{(3\cdot x +5) + [1+(-1)]}{x+2} Existence of additive inverse/Associative property

4) \frac{(3\cdot x + 6)+(-1)}{x+2} Definition of addition/Commutative and associative properties

5) \frac{3\cdot (x+2)}{x+2} + \left(-\frac{1}{x+2} \right)   \frac{a+b}{c} = \frac{a}{c} + \frac{b}{c}/ \frac{-a}{b} = \frac{a}{-b} = -\frac{a}{b}/Distributive property

6) 3 -\frac{1}{x+2} Definition of division/Existence of multiplicative inverse/Modulative property/Definition of subtraction/Result

The quotient of the rational function is 3 -\frac{1}{x+2}.
