Please help! It's due in 30 mins!! Here is my question
There are 5 chains ith the length of 0.31m, 0.7m, 0.14m, 0.027m and 0.2m. Which chains could you put together to have a total length of about 0.5m (You can us the same chain more than once)

Respuesta :

About 50 - all-round 50

0.31m+.2m=0.51m

If subtraction is allowed (.7m-.2m=0.5m)

0.14+.31+ 0.027=0.477

0.14+.31=0.45
