A unit rate is basically the same as a unit cost like for example if you buy 10 dogs for 1000 dollars total then its 1000/10 and each dog is $100. since its 100 for each dog its 100/1 so the unit cost is $100
This is a ratio problem
6 / 800 = 9 / n (can say as 6 is to 800g as 9 is to n grams)
6n = 800(9) --- by multiplying means and extremes
n = 7200 / 6 divide by 6 to isolate n
n = 1200g
plug in to check 6 / 800 = 0.0075 9 / 1200 = 0.0075
125/1924 is the fraction when you divide those two numbers
Answer:
2405
Step-by-step explanation:
From the fourth clue, we know that three of the digits are in 9245. From the first clue, we know that two of the digits are in 5310. Therefore, 5 must be one of the digits.
From the second clue, we know that two of the digits are in 2519. Since 5 is one of the digits, either 2 or 9 is another digit, but not both. We also know that 1 is not a digit.
Since 5 is a digit and 1 is not a digit, we know from the first clue that either 3 or 0 is a digit, but not both. From the fifth clue, we know that neither 9 or 6 is a digit. Therefore, 2 is a digit. And from the third clue, we know that neither 7 nor 8 is a digit.
From the sixth clue, we know that 4 and 0 are digits, and that they are the hundreds and tens place, respectively. So the number is either 5402 or 2405. From the first or second clue, we know that it is 2405.
