The answer is 52.5 because you are suppose to multiply each number in pairs. First multiply 21/61 times 5/8.Then you will get 105/488. Multiply 105/488 times 244/1 which equals 25,620/488. Simplify to the lowest form which equals 6,405/122. Divide 6,405 divided by 122. The answer will be 52.5. That is how you will get the answer.

Answer:
The answer is below
Step-by-step explanation:
For the first clock that is 20 minutes faster in a day, that means it is
faster every day. For it to show the correct time, the clock should be 24 hours faster.
Since 1 day = 1/3 hr faster
x days = 24 hr faster
Let x number of days be required to be 24 hr faster. To find x we use the formula:

For the second clock that is 30 minutes slower in a day, that means it is
faster every day. For it to show the correct time, the clock should be 24 hours slower.
Since 1 day = 1/2 hr slower
y days = 24 hr faster
Let x number of days be required to be 24 hr slower. To find x we use the formula:
