Question

7целых 1/9 : 11 целых 1/4

Answer 1

7 1/9 : 11 1/4 = 34/9 : 45/4 = 34/9 * 4/45 = (34*4)/(9*45) = 256/405

Answer 2

To find the difference between 7 and 1/9 and 11 and 1/4, we need to convert both mixed numbers to improper fractions and then subtract them.

7 and 1/9 can be written as (79 + 1)/9 = 64/9 11 and 1/4 can be written as (114 + 1)/4 = 45/4

So, the difference between the two is:

64/9 - 45/4

To subtract these fractions, we need to find a common denominator. The least common multiple of 9 and 4 is 36. So, we can rewrite the fractions with 36 as the denominator:

(64/9) * (4/4) = 256/36 (45/4) * (9/9) = 405/36

Now we can subtract the fractions:

256/36 - 405/36 = -149/36

Therefore, the difference between 7 and 1/9 and 11 and 1/4 is -149/36 or approximately -4.14.
