Question

how many 3/4 foot lengths of pipe can be cut from a 7 and 1/2 foot pipe?


please show your work!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Answer:

The number of pipes to be cut from total length of pipe is 10 pipes

Step-by-step explanation:

Given as :

Total length of pipe = l =  7$\frac{1}{2}$ foot

i.e ' = $\frac{15}{2}$  foot

The length of pipe to be cut = l' = $\dfrac{3}{4}$ foot

Let The number of pipes to be cut = n pipes

According to question

The number of pipes to be cut = $\dfrac{\textrm Total length of pipe}{Length of pipe to be cut}$

i.e n = $\dfrac{l}{l'}$

Or, n = $\frac{\frac{15}{2}}{\frac{3}{4}}$

Or, n = $\frac{15\times 4}{3\times 2}$

or, n = 5 × 2

∴ n = 10 pipes

So, The number of pipes to be cut = n = 10 pipes

Hence, The number of pipes to be cut from total length of pipe is 10 pipes Answer
