1.1.1 To convert from g to kg: 1000g are equal to 1kg:
[tex]300g\cdot\frac{1kg}{1000g}=0.3\operatorname{kg}[/tex]300 g is equal to 0.3 kg
1.1.2. As the recipe is for serving 2 people and Jane needs to make it for 5 people:
Use the next to find how many kg of tomatoes be needed:
[tex]5\text{people}\cdot\frac{400g}{2\text{people}}\cdot\frac{1\operatorname{kg}}{1000g}=1\operatorname{kg}[/tex]
Jane will need 1kg of tomato
1.1.3 To convert mL into L: 1000mL are equal to 1L
[tex]500mL\cdot\frac{1L}{1000mL}=0.5L[/tex]500mL is equal to 0.5L
1.1.4 r=7cm h=5cm
1 square centimeter is equal to 1 mL, or equal to 0.001L
[tex]\begin{gathered} C=\pi\cdot r\cdot r\cdot h \\ C=3.14\cdot7\operatorname{cm}\cdot7\operatorname{cm}\cdot5\operatorname{cm} \\ C=769.3cm^3 \\ \\ \\ 769.3cm^3\cdot\frac{1mL}{1cm^3}\cdot\frac{1L}{1000mL}=0.7693L \end{gathered}[/tex]The capacity of the pot is 0.7693L1.2
1.2.1.
[tex]300g\cdot\frac{1\operatorname{kg}}{1000g}\cdot\frac{2.2lb}{1\operatorname{kg}}=0.66lb[/tex]300 g is equal to 0.66lb
1.2.2
[tex]1floz\cdot\frac{500mL}{17.6056fl\mathrm{}oz}=28.4mL[/tex]
1 fl.oz is equal to 28.4mL
1.2.3
[tex]810\operatorname{km}\cdot\frac{1mi}{1.609\operatorname{km}}=503.41mi[/tex]Then, the distance is approximately 500 miles (503.41 miles)
1.2.4
[tex](34ºC\cdot\frac{9}{5})+32=93.2ºF[/tex]
1.3.1
[tex]875L\cdot\frac{1000cm^3}{1L}\cdot\frac{1mL}{1cm^3}=875000mL[/tex]
1.3.2
[tex]35.853cm^3\cdot\frac{1L}{1000cm^3}=0.035L[/tex]
