Answer:
7:13
Step-by-step explanation:
Since Eli has 7 games and his sister has 6 more than him, first you would add 7 to 6 and would get 13.
7 + 6 = 13
After you add, since the question is asking which ratio compares the number of games on Eli's phone compared to the number of games on his sister's phone, the number of Eli's games would go first, and then his sister's number of games would be the second number in the ratio, leaving you with 7:13.
All you have to do is 1000 divide 231
You will get the answer 0.231
Than you move the decimal point 2 times to the right
So the percentage is 23.1%
Their least common multiple is 90 .
90 = 5 x 18
90 = 2 x 45
Answer:
The percent change in Nancy height is 10%
Step-by-step explanation:
Given : when Nancy started middle school, she was 60 inches tall. when she started high school, she was 66 inches tall.
We have to find the percent change in her height.
Percentage change is given by the ratio of the difference in old value and new value to the old value times 100
Mathematically written as
![Percentage\ change =\frac{new\ value-old\ value}{Old\ value}\times 100](https://tex.z-dn.net/?f=Percentage%5C%20change%20%3D%5Cfrac%7Bnew%5C%20value-old%5C%20value%7D%7BOld%5C%20value%7D%5Ctimes%20100)
For the given data,
Old value = 60 inches
New value = 66 inches
Thus, the Percentage change is given as,
![Percentage\ change =\frac{66-60}{60}\times 100](https://tex.z-dn.net/?f=Percentage%5C%20change%20%3D%5Cfrac%7B66-60%7D%7B60%7D%5Ctimes%20100)
Simlify, we have,
![Percentage\ change =\frac{6}{60}\times 100](https://tex.z-dn.net/?f=Percentage%5C%20change%20%3D%5Cfrac%7B6%7D%7B60%7D%5Ctimes%20100)
Thus, The percent change in her height is 10%
