Marissa is ordering - 1/6, -1/3, 1.4, 0.2, 2/3 from least to greatest. here are her steps:

(1) write each decimal as a fraction.

(2) write every fraction with a common denominator of 18.

(3) plot the numbers on the number line.

(4) list the numbers from left to right as they are plotted on the number line.

identify any and all errors that marissa made in her steps.

marissa should have only plotted the fractions on the number line.

marissa should have used 30 as the common denominator.

marissa should have listed the numbers from right to left after she plotted them on the number line.

marissa should have used a common denominator of 30 and should have listed the numbers from right to left after she plotted them on the number line.

B.) Marissa should have used 30 as the common denominator.

ANSWER EXPLAINED BELOW

Step-by-step explanation:

1) 1.4 = 7/5

0.2 = 1/5

2) since the question requires denominator to be 18 we will multiply the numerator and denominators will the required number to make it 18

-1x3/6x3= -3/18

-1x6/3x6= -6/18

2x6/3x6 = 12/18

3) Arrange all the numbers from least to greatest in decimal

-0.33, -0.167, 0.2, 0.667, 1.4            

number line

  °                     °                                                            °                     °    

-0.3   -0.25    -0.2   -0.15   -0.10   -0.1   -0.05   0   0.5   0.1   0.15  0.2

Marissa should have used a common denominator of 30 and should have listed the numbers from right to left after she plotted them on the number line.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question
