A metal rod will be cut into pieces that are each 1/56 meters long. The rod is 7/8 meters long. How many pieces will be made fro
S_A_V [24]

The number of pieces made from rod is 49

<h3><u>Solution:</u></h3>

Given that A metal rod will be cut into pieces that are each 1/56 meters long

The rod is 7/8 meters long.

<em><u>To find: number of peices made from rod</u></em>

The number of peices made from rod can be calculated by dividing the total length of rod by length of each piece

\text {number of pieces made }=\frac{\text {total length of rod }}{\text { length of each piece}}

Here total length of rod = \frac{7}{8} meters

length of each piece to be made = \frac{1}{56} meters

Substituting the values in above formula, we get

\text {number of pieces made }=\frac{\frac{7}{8}}{\frac{1}{56}}=\frac{7}{8} \times \frac{56}{1}

\text {number of pieces made }=7 \times 7=49

So the number of pieces made from rod is 49
