This question isn't phrased correctly, but I will assume it's asking about common denominators with fractions.
9/11 1/22
18/22 1/22
18 school days.
Answer:
Step-by-step explanation:
You take the starting year of 1990 and subtract it from 1999 to get the year span of 9,
You then take the amount per year the population goes up by which is 300, so 300 multiplied by 9 is 2,700
You add 2,700 to 21,152 to get B-23,852
Let's set up some simultaneous equations. Let the number of nickels be n, and the number of quarters be q. Now I'm from England so I had to look up the value of a nickel (I could guess the quarter though to be 25c), but apparently it's 5c
Okay we know that the total value of the coins is 150. This gives:
25q + 5n = 150
Rearranging to make n the subject:
n = 30 - 5q
Next, we use the second statement:
n = 2q - 5
Substituting this into the first equation:
2q - 5 = 30 - 5q
7q = 35
q = 5
Putting this value for q into the first equation:
n = 30 - 5(5) = 5
Hence he has 5 of each coin. I hope this helps :)
Answer:
37
Step-by-step explanation:
We start by reducing the ratio to its smallest value. This is the same as 1:14
We know from the question that the number of apple eater takes the 14 ratio part. We can make the calculations for the total number first then make a subtraction to get the number of apple eaters.
Firstly, we add the ratios together:
1 + 14 = 15
Let the total number of reindeers be T
14/15 * T = 517
T = (15 * 517)/14 = 554
To get the the number of apple loving Reindeers, we then subtract.
This is 554 - 517 = 37
