Step-by-step explanation: The total number of pizzas is 12 + 18 = 30. Mitchel bought 12 of those 30 pizzas. To find the percentage you do the portion/total. Thus 12/30 = 0.4, as a proportion. To turn a proportion into a percentage simply multiply by 100. 0.4 * 100 = 40%
7 spaces total
7 × 1cm = 7cm
6 box cars
6 × 7cm = 42cm
1 engine
1 × 12cm = 12cm
7cm + 42cm + 12 cm = 61cm
The train is 61cm long.
