Put these fractions in order least to greatest. 4/6 1/3 and 1/5
stiv31 [10]

Answer:

1/5 < 1/3 < 4/6

Step-by-step explanation:

Using the given inputs:

4/6 1/3 1/5

The least common denominator (LCD) is: 30.

Rewriting as equivalent fractions with the LCD:

4/6 1/3 1/5

20/30 10/30 6/30

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

1/5   1/3   4/6

6/30 < 10/30 < 20/30

Therefore, the sorted inputs in order from least to greatest is:

1/5 < 1/3 < 4/6

The difference of nine, and a number divided by four is 13.
AveGali [126]

Answer:

I think -16

Step-by-step explanation:

First you subtract 9 from both sides giving you 4 on the right side. Next you multiply each side by the reciprocal which in this case would be -4/1 or -4. This gives you just the letter n on the left and -16 on the right.
