Rita purchased a ribbon of 8 1/2 m length. If she divided into 5 pieces of equal length, find the length of one piece.

Answer»

Given :

Ribbon = 8 1/2
Dividing by = 5

To find :

LENGTH of one piece.

Solution :

Now, we have to divide the 8 1/2 meters of ribbon by 5. So, to do that, we have to FIRST convert the following Mixed Fraction to Improper fraction. And let's do it.

First, multiplying 8 and 2. Then, adding 1.

$\sf 8 \dfrac{1}{2} \rightarrow \dfrac{8 \times 2 + 1}{2 }$

$\sf \rightarrow \dfrac{16 + 1}{2 }$

$\sf \rightarrow \dfrac{17}{2 }$

Therefore, 8 1/2 when converted to an improper fraction is 17/2.

Let's divide 17/2 by 5.
Here, multiplying 5 and 2 and we get 10. Then, we must divide it by 10. And we get 1.7 meters as the final answer.

$\sf \rightarrow \dfrac{17}{2} \div 5$

$\sf \rightarrow \dfrac{17}{2 \times 5 }$

$\sf \rightarrow \dfrac{17}{10 }$

$\sf \rightarrow 1.7$

Therefore, 8 1/2 meters of ribbon when DIVIDED by 5 is 1.7 meters.
