How many pieces each of length 4 4/1m can be cut out of a rope of length of 68m
Answers
Answer:
8 pieces can be cut.
Step-by-step explanation:
Length of rope = 30m
Length of piece cut =
\begin{gathered}3 \frac{3}{4} = \frac{(4 \times 3) + 3}{4} = \frac{15}{4} m \\\end{gathered}

\begin{gathered}number \: of \: pieces \: that \: can \: be \: cut \: = \frac{length \: of \: rope}{length \: of \: piece \: cut} \\ = \frac{30}{ \frac{15}{4} } \\ = 30 \times \frac{1}{ \frac{15}{4}} \\ = 30 \times \frac{4}{15} \\ = 15 \times 2 \times \frac{4}{15} \\ = 4 \times 2 \\ = 8\end{gathered}

Answer:
1. if u mean 4 m then 17 pcs
2. if u mean 4 4/1 then 8
Step-by-step explanation:
1.
length of;
rope = 68 m
each piece = 4 m
total pcs = 68 ÷ 4
= 17
a total of 17 pieces can be cut out of the rope
.
.
2.
length of;
rope = 68 m
each piece = 4 4/1m
= 4 + 4m
= 8 m
total pcs = 68 ÷ 8
= 8 (r - 4 m)
a total of 8 pieces (with a remainder of 4 m rope) can be cut out of the rope
