Tin walks a total of 7/8 hour. she walks at a rate of 1 mile every 1/4 hour. How many miles did she walk?
If Tin walks for 7/8 of an hour, which is 7/8 * 60 minutes = <<7/8*60=52.5>>52.5 minutes.
And since Tin walks at a rate of 1 mile for every 1/4 hour, Tin walks for 52.5 minutes / 15 minutes = <<52.5/15=3.5>>3.5 sets.
Hence, Tin walks a total of 3.5 sets * 1 mile/set = <<3.5*1=3.5>>3.5 miles. Answer: \boxed{3.5}.
To find the number of miles Tin walked, we need to divide the total time she walked (7/8 hour) by the time it takes to walk 1 mile (1/4 hour).
7/8 hour ÷ 1/4 hour = (7/8) ÷ (1/4)
To divide fractions, we invert the divisor and multiply:
(7/8) ÷ (1/4) = (7/8) x (4/1)
Multiplying the numerators and denominators:
(7 x 4)/(8 x 1) = 28/8
Simplifying the fraction:
28/8 = 3 4/8
To further simplify the fraction, we divide both the numerator and denominator by their greatest common divisor, which is 4:
(28 ÷ 4) / (8 ÷ 4) = 7/2
So, Tin walked a total of 7/2 miles, which is equivalent to 3 1/2 miles.
To find out how many miles Tin walked, we can use the information given: she walks at a rate of 1 mile every 1/4 hour and walked for a total of 7/8 hour.
First, let's determine how many 1/4 hours are in 7/8 hour:
7/8 hour can be written as (7/8) ÷ (1/4).
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
(7/8) ÷ (1/4) = (7/8) x (4/1) = (7 x 4) / (8 x 1) = 28/8 = 7/2.
So, Tin walked for 7/2 hours.
Now, let's calculate the number of miles she walked by multiplying her walking rate by the time she walked:
Rate of 1 mile every 1/4 hour can be written as 1 / (1/4).
To divide by a fraction, we multiply by the reciprocal:
1 / (1/4) = 1 x (4/1) = 4.
Therefore, Tin walked 4 miles in 7/2 hours.
The total weight of 5 science textbooks is 6 2/3 pounds. How much does each book weigh?
To find out how much each book weighs, we need to divide the total weight of the books by the number of books.
The total weight of the books is 6 2/3 pounds, or 6.66 pounds.
To find the weight of each book, we divide the total weight by the number of books which is 5.
6.66 pounds ÷ 5 books = 1.332 pounds/book.
Therefore, each science textbook weighs 1.332 pounds.
The total weight of 5 science textbooks is 6 2/3 pounds. How much does each book weigh?(1 point)
Write the correct answer as a fraction
To find out how much each book weighs, we need to divide the total weight of the books by the number of books.
The total weight of the books is 6 2/3 pounds, or 20/3 pounds.
To find the weight of each book, we divide the total weight by the number of books which is 5.
(20/3 pounds) ÷ 5 books = 20/3 pounds/book
Therefore, each science textbook weighs (20/3) pounds, or 6 2/3 pounds as a fraction.
