Question

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

Answer 1

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 \frac{4\text{ cans of coffee}}{4} = (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 \frac{1 \text{ can of coffee}}{4} = (0.4)/(4) \iff (1)/(4)\text{ cans of coffee} = 0.1`
