Question

10. Make Sense and PersevereLynn filledeach of three bags with 2 kilograms450 grams of sand. Is the mass of 2 bagsgreater than or less than 5 kilograms?

Answer 1

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given measures of the bag of sand

`\begin{gathered} \text{Lynn filled each of thre}e\text{ bags, this means that;} \\ 1\text{ bag = 2 kilograms and 450 grams of sand.} \\ \text{2 kilograms and 450 grams}\Rightarrow2kg+0.450kg=2.450kg \\ \\ \therefore1\text{ bag = }2.450kg \end{gathered}`

STEP 2: Get the mass of 2 bags

`\begin{gathered} \text{Mass of 1 bag =2.450}kg \\ \text{Mass of 2 bags will be }2*2.450=4.9kg \end{gathered}`

STEP 3: Make a conclusion

`\begin{gathered} It\text{ can be s}een\text{ that;} \\ 4.9kg<5kg \end{gathered}`

Hence, the conclusion is that the mass of 2 bags is less than 5 kilograms.

This is known by finding the mass of 2 bags after knowing the mass of one bag (in kilograms) and check to see if the mass of the 2 bags are bigger or smaller than 5 kilograms. We saw that the mass of the two bags are smaller in terms of mass in Step 3.
