What does 1/4 of a can of coffee cost if 4 cans of coffee cost $1.60

Arte-miy333 [17]

We know that 4 cans of coffee cost $1.60. So, if we divide that number by 4, we get

$4\text{ cans of coffee} = 1.60 \iff \dfrac{4\text{ cans of coffee}}{4} = \dfrac{1.60}{4} \iff 1 \text{ can of coffee} = 0.4$

Now we can simply repeat this process again: if we divide both sides by 4, we get

$1 \text{ can of coffee} = 0.4 \iff \dfrac{1 \text{ can of coffee}}{4} = \dfrac{0.4}{4} \iff \dfrac{1}{4}\text{ cans of coffee} = 0.1$
