anonymous · Answer

next use dimensional analysis do you know what this is?

anonymous · Answer

noo sorry

anonymous · Answer

alright basically dimensional analysis is using proportions/ratios of measurement to switch to different types of measurement

anonymous · Answer

i'll give you an example, say you have  5 inches and you want to get this into centimeters


you know that

1inch = 2.14 cm so the ratio can be written either as

$$\frac{1inch}{2.14cm}$$
or
$$\frac{2.14cm}{1inch}$$

anonymous · Answer

these ratios will be used to cancel out terms first start out with whta they give you, my example it is 5 inches
