What is the length of this ruler to the correct degree of precision? 16 mm 1.61 cm 1.61 mm 1.610 cm

16 mm

Step-by-step explanation:

Knowing that the longest lines with the numbers marked on them is the tens, I realized there was only one line the red line crossed. The other 6 was from one little mm and the med-long line.

If you will look at the red line that is spread on the ruler,if measured with divider , it will lie between 1.6 cm to 1.7 cm.

1 cm =10 mm

Coming to the Options

---The length of the Red Ruler can be 16 mm.

---1.61 cm and 1.610 cm are same length.

---1.61 mm is rejected.

But from this kind of ruler you can't say with exact degree of Precision that length will be either 1.61 cm or 1.610 cm.Because it can't measure 1.61 cm.The scale can measure lengths upto a single decimal place that is upto tenths.

So, the  length of this ruler to the correct degree of precision will be = 16 mm =1.6 cm

Option A

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
