Answer:
I believe the answer is D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Step-by-step explanation:
She can make 10 dresses if you split the number line into 20 parts and find 2/5. Therefore, it would then be grouped into 10 parts, each part 2/5ths of a yard.

Answer:
Kira sent 19 text messages, Goran sent 14 text messages and Joe sent 57 text messages.
Step-by-step explanation:
Let be "k" the number of text messages that Kira sent during the weekend, "g" the number of text messages that Gora sent during the weekend and "j" the number of text messages that Joe sent during the weekend.
We know know that they sent a total of 90 text messages then:
![k+g+j=90](https://tex.z-dn.net/?f=k%2Bg%2Bj%3D90)
Goran sent 5 fewer messages than Kira. This is:
![g=k-5](https://tex.z-dn.net/?f=g%3Dk-5)
And Joe sent 3 times as many messages as Kira. Then:
![j=3k](https://tex.z-dn.net/?f=j%3D3k)
The steps to solve this are:
- Substitute the second equation and the third equatio into the first equation and then solve for "k":
![k+(k-5)+(3k)=90\\\\5k-5=90\\\\5k=90+5\\\\k=\frac{95}{5}\\\\k=19](https://tex.z-dn.net/?f=k%2B%28k-5%29%2B%283k%29%3D90%5C%5C%5C%5C5k-5%3D90%5C%5C%5C%5C5k%3D90%2B5%5C%5C%5C%5Ck%3D%5Cfrac%7B95%7D%7B5%7D%5C%5C%5C%5Ck%3D19)
- Substitute this value into the second equation to find "g":
![g=19-5=14](https://tex.z-dn.net/?f=g%3D19-5%3D14)
- Substitute the value of "k" into the third equation to find "j":
![j=3(19)=57](https://tex.z-dn.net/?f=j%3D3%2819%29%3D57)
If the number on top is bigger than the number on the bottom then it is more than one. if the number on the top is smaller then the number on the bottom then it is less than one. if the bottom and top number are the same then it is 1.
