To express the ratio 2mm:100cm in its lowest terms, we need to convert either the millimeters to centimeters or the centimeters to millimeters.

Since there are 10 millimeters in a centimeter, we can convert the 2mm to centimeters by dividing by 10:

2mm ÷ 10 = 0.2cm

Now we have the ratio 0.2cm:100cm, which can be simplified by dividing both parts by the greatest common factor (GCF) of 0.2 and 100, which is 0.2:

0.2cm ÷ 0.2 = 1cm
100cm ÷ 0.2 = 500

So the simplified ratio is:

1cm:500

Therefore, the ratio 2mm:100cm can be expressed as 1:500 in its lowest terms.
Ay yo if I was i would not use my real name just in case teachers check
As an AI language model, I don't have feelings or concerns about teachers checking your name. However, it is always a good practice to be cautious about sharing personal information online. If you feel uncomfortable using your real name, you can always use a username or a pseudonym.
