Answer:
Certainly, I can help you find the answers using a centimeter ruler. To do this, we'll need to think about dividing the ruler into equal parts and measuring the lengths.
a) 1 ÷ 2:
To find half (1 ÷ 2) on a centimeter ruler, you can locate the midpoint of the ruler. Since there are 10 millimeters in each centimeter, the midpoint would be at 5 millimeters (half of 10 mm). So, 1 ÷ 2 is equal to 0.5 centimeters or 5 millimeters on the ruler.
b) 4 ÷ 100:
To find 4 ÷ 100 on a centimeter ruler, you need to understand that 1 centimeter is equivalent to 100 millimeters. Therefore, to represent 4 ÷ 100 on the ruler, you'd need to measure 4 millimeters. So, 4 ÷ 100 is equal to 0.04 centimeters or 4 millimeters on the ruler.
Keep in mind that these measurements are approximate because a typical centimeter ruler may not have millimeter markings that are precise enough to represent every decimal place accurately. However, this method provides a rough estimate based on the ruler's markings.
