Maths Problem Solving

This is Maths Problem Solving And I have made it with my friend adriel have solved to question in this presentation. In the first question we have not did that many steps because we had a smaller way to get the answer and we did 7 divided by 2 = 3 1/2 In this next question I have solved it by using time tables and finding our 2/5 of 30 because 5 x 6 = 30 so 6 x 2 = 12 so the answer is 12.
