uysha [10]

Answer:

3:4.

Step-by-step explanation:

To work this out we need to find the highest multiple of 45 and 60.

55.27 is the same as 55 ____' 12".
choli [55]
<span><span>27100</span>(60)=<span>815</span>=16<span>15</span></span> The 16 is how many minutes you have. If you were not given the seconds, we would have to say that we have a remainder of (1/5) of a minute. Since 1 minute is (1/60), one-fifth of that is (1/300). Now we would need to see how many seconds that gives us. 1 second is (1/3600) of a degree, so we would need to divide (1/300) by (1/3600). Doing this gives us: <span><span><span>1300</span>÷<span>13600</span>=<span>1300</span>(3600)=12</span></span>
