Question

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

Answer 1

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

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(1)/(2)=(4*2+1)/(2)=(9)/(2)`

`(140)/((9/2))=(280)/(9)`

Convert to mixed number

`(280)/(9)=(279)/(9)+(1)/(9)=31(1)/(9)\ times`

therefore

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