Question

Harold bought 5 apples for $1.30. What is the unit price?

Answer 1

Unit price for apple is `26` cents or `$0.26`.

Explanation:

`5` apples cost `$1.30` or `100+30=130` cents

Hence, unit price for apple is `130/5=26` cents or `$0.26`.

Answer 2

$0.26

Explanation:

The `color(blue)"unit price"` means 'what is the cost of 1 apple'?

`5" apples"to$1.30`

To find the cost of 1 apple `color(blue)"divide by 5"`

`1" apple" to($1.30)/5=$0.26`

Answer 3

The relationship between the shortcut method and ratio.

`color(green)("The unit ( for 1 of them) price is $0.26")`

Explanation:

Express the ratio in fraction form.

`("cost")/("count") ->($1.30)/5`

But we need `" "("cost")/1`

`=>("cost")/1 -> ($1.30-:5)/(5-:5) = ($0.26)/1`

`"So the unit ( for 1 of them) price is $0.26"`
