Question

Oliver has 5 pieces of string that are each 4 . feet long. Destinyhas 4 pieces of string that are each 5 to feet long. Use anestimation strategy to determine who has the most string.Choose the name and number to complete the statement.

Answer 1

Explanation:

Oliver has 5 pieces of string, each of length 4 2/12 feet.

`\begin{gathered} 4(2)/(12)=4+(2)/(12) \\ (2)/(12)\text{ is closer to 0 than 1. } \\ \text{Therefore:} \\ 4(2)/(12)=4+(2)/(12)=4+0\approx4\text{ ft.} \end{gathered}`

Thus, the estimated total length of string Oliver has is:

`5*4=20\text{ feet}`

Next, Destiny has 4 pieces of string that are each 5 14/16 to feet long.

`\begin{gathered} 5(14)/(16)=5+(14)/(16) \\ (14)/(16)\text{ is closer to }(16)/(16)=1\text{ than to 0. Therefore:} \\ 5(14)/(16)\approx5+(16)/(16)=5+1=6 \end{gathered}`

Thus, the estimated total length of string Destiny has is:

`4*6=24\text{ feet}`

Finally. determine who has the most string and the length.
