Question

Which of the following is not true5000 kg is equal to approximately 5 tonne1 week is 10080 minutes 3 cL is equal to 30 mL

Answer 1

We can check the truth of each statement by converting the first value and comparing it with the other.

STATEMENT 1: 5000 kg and 5 tonne

The conversion rate of kg to tonne is given to be:

$1\operatorname{kg}=0.001\text{ tonne}$

To convert 5000 kg to tonnes, we will multiply the value by 0.001.

Thus, we get:

$\Rightarrow5000\times0.001=5\text{ tonnes}$

Therefore, THIS STATEMENT IS TRUE.

STATEMENT 2: 1 week and 10080 minutes

We can calculate the conversion from week to minutes by doing the following analysis:

$\begin{gathered} 60\text{ minutes }\Rightarrow1\text{ hour} \\ 24\text{ hours }\Rightarrow1\text{ day} \\ 7\text{ days }\Rightarrow1\text{ week} \end{gathered}$

Therefore, the conversion rate becomes:

$\begin{gathered} 60\times24\times7=10080 \\ \therefore \\ 10080\text{ minutes }\Rightarrow1\text{ week} \end{gathered}$

Therefore, THIS STATEMENT IS TRUE.

STATEMENT 3: 3 cl and 30 ml

The conversion rate for centiliters (cl) to milliliters (ml) is given to be:

$1\text{ cl }\Rightarrow10\text{ ml}$

Therefore, we can convert 3 cl to ml as follows:

$3\times10=30\text{ ml}$

Therefore, THIS STATEMENT IS TRUE.
