What is 55 1/5 - 32 3/4
garik1379 [7]

Answer:

449/20 or 22 9/20

Step-by-step explanation:

Change them to mixed numbers.

55 x 5 = 275 + 1 = 276

32 x 4 = 128 + 3 = 131

Then, convert them to a common denominator.

276 x 4 = 1104

131 x 5 = 655

1104 - 655 = 449

449/20

Ernest rode his bike 8 1/4 hours on Saturday and 6 1/4 on sunday he rode for a total of 88 1/2 miles for both days how long does
irina [24]
Saturday and Sunday: 8 1/4 hours + 6 1/4 hours = 33/4 + 25/4 = 58/4 = 29/2 hours = 14 1/2 hours

A total of 88 1/2 miles = 177/2 miles for both days.

If you would like to know how long does it take him to ride one mile on his bike, you can calculate this using the following steps:

88 1/2 miles ... 14 1/2 hours
1 mile ... x hours = ?

88 1/2 * x = 1 * 14 1/2
177/2 * x = 29/2      /*2
177 * x = 29            /177
x = 29/177 hours
x = 0.16 hours

Result: It takes him 0.16 hours to ride one mile on his bike.
