Question

From a rope 68 m long, pieces of equal size are cut. If length of one piece is 4¹/⁴ find the number of such pieces.​

Answer 1

Answer:

$\frac{68}{ \sqrt[4]{4} } = \frac{68}{(2 {}^{2} ) \frac{1}{4} } = \frac{68}{(2) \frac{1}{2} } = \frac{68}{ \sqrt{2} } = \frac{68 \times \sqrt{2} }{2} = 34 \sqrt{2} \: \: pieces \: is \: the \: answer$

that means 48 pieces (while multiply the 34x√2)
