There is no such thing as a nearest significant figure. For sf (as with decimal places) it is necessary to specify how many. 0.00747 to 1 sf is 0.007, to 2 sf it is 0.0075, to 3 sf it is 0.00747, to 4 sf it is 0.007470 and so on.
Rounded to 1 significant figure it is 0.4
6694 rounded to 1 significant figure is 7000
0009999 = 9999 is closer to 0.5
Rounding a number to the nearest significant figure means rounding it to the nearest digit that indicates the precision of the measurement. This typically involves looking at the significant figures in the number and rounding to the appropriate level of precision. For example, 345.678 rounded to the nearest significant figure would be 300.

You round to the nearest tens place. In this case, 738 rounded to one significant figure is 700.
The number 46313 rounded to 1 significant figure is 50000. The significant digit is 5, so the number is rounded up to the nearest power of 10.
To express 961 to one significant figure, you round it to the nearest significant digit. The first significant digit in 961 is 9, and since the next digit (6) is 5 or greater, you round up. Therefore, 961 rounded to one significant figure is 1000.
When expressing a number to one significant figure, you round the number to the nearest power of 10. In this case, 9862 to one significant figure would be 10,000. This is because the first digit from the left is 9, which is closer to 10 than 10000.
I think your question is asking how you would round 17.521 to the nearest number with 1 significant figure...if that's the case, it would round to 10.
When expressing a number to one significant figure, you round it to the nearest power of 10. In this case, 150.932 to 1 significant figure would be 200. Since 150.932 is closer to 200 than to 100, the rounded value is 200.
