A mechanic is using a machine that makes metal parts. She measures each part to confirm it is the correct size. Negative numbers
Hunter-Best [27]

Answer:

A

Step-by-step explanation:

In the figure attached, the complete question is shown.

We have to transform all the fractions to new fractions with the same denominator, as follows:

1/8 *4/4 = 4/32

-3/16 *2/2 = -6/32

-1/4 *8/8 = -8/32

1/32

5/32

-1/16 *2/2 = -2/32

Now we can order the list simply comparing numerators:

-8/32, -6/32, -2/32, 1/32, 4/32, 5/32

or

-1/4, -3/16, -1/16, 1/32, 1/8, 5/32

From the question ;

When reducing percentages, division is employed and this the equation should be :

40/2 ÷ 100/2

40/2 * 2/100

20 * 1/50

20/50

= 0.4

0.4 * 50

= 20 students
