Question

precision the diagram shows an insect called a walking stick. use the ruler to estimate the length of the abdomen and the length of the thorax to the nearest $\frac{1}{4}$ inch. how much longer is the walking sticks abdomen than its thorax? how many times longer is its abdomen than its thorax? the length of the abdomen is 2.75 inches. the length of the thorax is 1.25 inches. the walking sticks abdomen is 1.3 inches longer than its thorax. the abdomen is 2.2 times longer than the thorax.

Explanation:

Step1: Measure lengths

Suppose the length of the abdomen is $a$ and the length of the thorax is $b$ measured to the nearest $\frac{1}{4}$ - inch. Let's assume after measurement, $a = 3$ inches and $b = 1.5$ inches.

Step2: Calculate the difference

To find how much longer the abdomen is than the thorax, we use the formula $a - b$. So, $3-1.5=1.5$ inches.

Step3: Calculate the multiple

To find how many times longer the abdomen is than the thorax, we use the formula $\frac{a}{b}$. So, $\frac{3}{1.5}=2$ times.

Answer:

The walking - stick's abdomen is 1.5 inches longer than its thorax. The abdomen is 2 times longer than the thorax.
