Question

How many 4 1/2 meters of ribbon are there in a 140 meter spool?​

Answer 1

Answer:

in a 140 meter spool there are 31 1/9 times 4 1/2 meters of ribbon

Step-by-step explanation:

To find out how many 4 1/2 meters of ribbon are there in a 140 meter spool, divide 140 meter by 4 1/2 meter, but first convert mixed number to an improper fraction

$4\frac{1}{2}=\frac{4*2+1}{2}=\frac{9}{2}$

$\frac{140}{(9/2)}=\frac{280}{9}$

Convert to mixed number

$\frac{280}{9}=\frac{279}{9}+\frac{1}{9}=31\frac{1}{9}\ times$

therefore

in a 140 meter spool there are 31 1/9 times 4 1/2 meters of ribbon
