Pls do 2 3 4 a and b
kirza4 [7]

Answer:

2.a)11.355 b)0.94625

3. divide 6 by 4

4. 0.8kg, 800g

Step-by-step explanation:

To convert one measurement to another you need to set it up so that the old measurement gets cancelled out when you multiply the conversion ratio.

2a)  \frac{3 gallons}{1} *\frac{3.785 milliliters}{1 gallon}=11.355 milliliters the gallons on top and bottom get cancelled out leaving you with the measurement that you want

2b) \frac{1quart}{1} *\frac{1 gallon}{4 quarts} *\frac{3.785 milliliters}{1 gallon} = 0.94625 milliliters

3) \frac{x}{y} \frac{6 quarts}{1} *\frac{1 gallon}{4 quarts} = 1.5 gallons

4) \frac{28 ounces}{1} *\frac{1 kilogram}{35 ounces} = 0.8 kilograms

\frac{0.8 kilograms}{1} *\frac{1000 grams}{1 kilogram} = 800 grams
