Jacob measured the length of a few classroom objects. a pen is 5 3/16 inches long, a stapler is 5 3/4 inches long and a stapler is 4 7/8 inches long. list the lengths in order from least to greatest.

4 7/8,  5 3/16 and 5 3/4.

Step-by-step explanation:

It will be easy to arrange them in order if we change all the fractions to one with a denominator of 16.

5 3/4  = 5 12/16       ( multiplying by 4/4).

4 7/8 = 4 14/16.       (multiplying by 2/2).

The third item is 5 3/16 long.

So we see that the list is  4 7/8, 5 3/16 and 5 3/4.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
