1. a) Sarah planted 4 rows of flowers in her garden. In each row, there are 5 flowers. How many flowers did Sarah plant in total?
Solution:
We need to find the total number of flowers. Since there are 4 rows and each row has 5 flowers, we multiply:
$$
4 \text{ rows} \times 5 \text{ flowers per row} = 20 \text{ flowers}
$$
✔ Answer: 20 flowers

1. b) If she wants to create 3 more rows, each with 5 flowers, how many flowers will she have in the end?
First, calculate the number of flowers in the 3 new rows:
$$
3 \text{ rows} \times 5 \text{ flowers per row} = 15 \text{ flowers}
$$
Now, add this to the original 20 flowers:
$$
20 + 15 = 35 \text{ flowers}
$$
✔ Answer: 35 flowers

2. a) Salim has 6 boxes of building blocks, and each box contains 8 blocks. How many building blocks does he have in total?
Multiply the number of boxes by the number of blocks per box:
$$
6 \text{ boxes} \times 8 \text{ blocks per box} = 48 \text{ blocks}
$$
✔ Answer: 48 blocks
---
2. b) If he shares an equal number of blocks with his two friends, how many blocks will each friend receive?
He is sharing the
total blocks (48) equally among
2 friends.
So divide:
$$
48 \div 2 = 24 \text{ blocks per friend}
$$
✔ Answer: 24 blocks each

✔ Final Answers Summary:
1. a)
20 flowers
1. b)
35 flowers
2. a)
48 blocks
2. b)
