Final answer:
For Question 1, there are 4 children sharing the marbles. For Question 2, Mina will have £3.60 left. For Question 3, Ben has saved 210p.
Step-by-step explanation:
Question 1:
27 marbles are shared among several children. Each child receives 6 marbles and there are 3 marbles left over. To find the number of children, we can divide the total number of marbles by the number of marbles each child receives. So, 27 ÷ 6 = 4 remainder 3. Since there are 3 marbles left over, it means there are 4 children sharing the marbles.
Question 2:
Mina has £7.20, and if she gives half to her brother, she will be left with half. To find out how much money she has left after giving half to her brother, we can divide £7.20 by 2. So, £7.20 ÷ 2 = £3.60. Therefore, Mina would have £3.60 left.
Question 3:
Ben saved seventeen 10p coins and two 20p coins. To find out how much money Ben has saved, we need to calculate the total value of the coins. Multiply the number of 10p coins by 10 and the number of 20p coins by 20. So, 17 x 10p + 2 x 20p = 170p + 40p = 210p. Therefore, Ben has saved 210p.
