Question

The instructions for building a kite tell you to begin by cutting a strip of wood to 45 cm in length, but your ruler only measures inches. How many inches should the piece of wood be? Round to the nearest quarter of an inch. (Recall: 1 in. = 2.54 cm)

Answer 1

If one inch = 2.54 centimeters, then 45 centimeters divided by 2.54 centimeters will give you the amount of inches the piece of wood needs to be.

45/2.54 = 17.72  ---- Rounded to the nearest quarter, would be 17.75 inches.

Answer 2

Answer:   $17\dfrac{23}{32}\text{ inches}$.

Step-by-step explanation:

Given: The required length of wood strip = 45 cm

Since we know that $\text{One inch = 2.54 centimeters}$

Using Unitary Method ,

$\text{One centimeter}=\dfrac{1}{2.54}\text{ inch}$

Now, the length of the strip ( in inches ) will be :-

$\dfrac{1}{2.54}\times45\text{ inches}\\\\\\=\dfrac{12512}{32}\text{ inches}\\\\\\=17\dfrac{23}{32}\text{ inches}$

Hence, the length of the piece should be $17\dfrac{23}{32}\text{ inches}$.
