When you solve a problem, you must choose which of these calculation methods is best to use: mental math, pencil and paper, or calculator.

\begin{tabular}{|l|l|}

\end{tabular}

Which methods would you use to solve these Tournament Records problems?

1. How many minutes did it take to reach the record for fencing?

[tex]$4 \times 60$[/tex] (I can do this using mental math.)

2. How many centimetres is the shot put record?

[tex]$27 \times 100$[/tex] (I think I'll use paper and pencil.)

Alright, let's break down the given problems step by step and decide on the best methods to solve each one.

1. Converting hours to minutes for fencing:
- We know that fencing took 4 hours.
- To convert hours to minutes, we multiply the number of hours by 60 (since there are 60 minutes in an hour).
- So, we need to calculate [tex]\(4 \times 60\)[/tex].

Since multiplying by 60 involves basic multiplication and is a straightforward calculation, we can indeed use mental math here. Performing the calculation:

[tex]\[ 4 \times 60 = 240 \][/tex]

So, it took 240 minutes to reach the record for fencing.

2. Converting metres to centimetres for the shot put record:
- The given distance for the shot put is 27 metres.
- To convert metres to centimetres, we multiply the number of metres by 100 (since there are 100 centimetres in a metre).
- So, we need to calculate [tex]\(27 \times 100\)[/tex].

Since this involves multiplying by 100, which can be quite efficiently done using basic arithmetic, it can be performed using paper and pencil for clarity and accuracy. Performing the calculation:

[tex]\[ 27 \times 100 = 2700 \][/tex]

So, the shot put record is 2700 centimetres.

Therefore, the detailed solutions are:
- It took 240 minutes to reach the record for fencing.
- The shot put record is 2700 centimetres.
