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
[tex]4\frac{1}{2}=\frac{4*2+1}{2}=\frac{9}{2}[/tex]
[tex]\frac{140}{(9/2)}=\frac{280}{9}[/tex]
Convert to mixed number
[tex]\frac{280}{9}=\frac{279}{9}+\frac{1}{9}=31\frac{1}{9}\ times[/tex]
therefore
in a 140 meter spool there are 31 1/9 times 4 1/2 meters of ribbon
