Step-by-step explanation:

x1 / y1 times x2 / y2 where are two fractions

x1/y1 times x2/y2 = x1 times x2 / y1 times y2 = z1 / z2 z is a new fraction

fractions multiply like regular wholes number, which can also be represented in fractional form

Examples:

2/1 times 3/1 = 2x3 /1x1 6/1

10/2 x 18/3 = 180/6 now look at 10/2 = 5 18/3 = 6 5x6 = 30

5 x 6 = 30

Now apply to your fractions:

3/7 x 4/5 = 3x4 / 7x5

12/35

Three 24-hour clocks show the time to be 12 noon. One of the clocks is always correct one loses a minute every 24 hours and one

Ganezh [65]

There is one clock that shows the right time so we do not have to worry about the one which is always correct.

Talking about the second clock that loses a minutes in every 24 hours (or in a day), so after 60 days (since it has lost 60 minutes because it is losing 1 minute everyday) it will show 11:00 a.m when it is exactly the noon.

So this way, in total it will take $60\times 24=1440$ days before it shows the correct noon.

Now, the third clock gains a minute every 24 hours (or in a day) , after 60 days (when it has gained 60 minutes or a complete hour) it will show 1:00 p.m when it is exactly the noon.

This way, it will take $60\times 24=1440$ days (since it has gained a minute everyday) when it shows the correct noon.

Therefore, it will take 1440 days before all the three clocks show the correct time again.
