At the hardware store 2/4 of the nails are size 2d and 1/4 of the nails are size 4d what fraction of the nails are either size 2d or 4d

of the nails are either size 2d or 4d

Step-by-step explanation:

we know that

of the nails are size 2d

of the nails are size 4D

so

To find the fraction of the nails that are either size 2d or 4d, sum plus

the correct answer is 5 6 and 7

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.
