<span>The area model simplifies understanding the given problem. To do this, we start by breaking down the numbers. We have values of 4.6 and 3.
First, let's consider the whole numbers for multiplication: Whole number of 4.6 => 4 whole number of 3 => 3
Next, we multiply the whole numbers: => 4 x 3 => 12 Then we compute the decimal portion: =>.6 x 3 => 1.8 Finally, add them together: => 12 + 1.8 = 13.8</span>
Adam and his dad split the bill in a 2:3 ratio. The dad’s share equals the 3 parts and is £52.20, so one part is 52.20 ÷ 3 = £17.40. Adam’s portion (2 parts) is 2 × 17.40 = £34.80. The total cost is 34.80 + 52.20 = £87.00.
