Guided practice
1. order the numbers from least to greatest.
50.1 * 10-3, 4.8 10-1, 0.52 * 10 3,56 10-2
a 0.52 * 10 3,50.1 103, 4.8 * 10-1, 56 * 10 2
ob 0.52 x 10-3,50.1 10-3,56 10 2 4.8 x 10-1
c 5.2 x 10-4,5.01 10 2,4.8 x 10 1,5.6 x 10-1

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
