What is 4/9 and 17/18 renamed using least common denominator?
dusya [7]

Answer:

8/18 & 17/18 is your answer.

Step-by-step explanation:

Find common denominators for both (you cannot simplify). Note that what you do to the denominator, you must do to the numerator. Find multiples of each number:

9: 9, 18

18: 18

The first least common denominator you get is 18. Solve:

(4/9)(2/2) = 8/18

8/18 & 17/18 is your answer.

PLEASE HELP WITH THIS QUESTION​
Vanyuwa [196]

Answer:

A

Step-by-step explanation:

2x < 8

x < 8/2

x < 4

The sign stays in the same direction since you are dividing by positive.  The circle is not filled in because x is NOT less than or equal to 4.
