Since the user options (ExplainAnswer, TeachTopic, GeneratePractice) are all set to false, I will skip those sections and proceed directly to solving a representative problem from the worksheet.
I have selected the word problem located in the bottom-right section of the middle row (the third column, second row down).
Problem:
"Amanda bought some material to make 6 curtains. She used 3.15 m for each curtain. She had 2.5m of material left after making the curtains. How many meters of material did she buy?"
Step-by-Step Solution:
1.
Calculate the total material used for the curtains:
* Number of curtains = 6
* Material per curtain = 3.15 meters
* Total used = $6 \times 3.15$
Let's do the multiplication:
$$3.15 \times 6$$
$$3 \times 6 = 18$$
$$0.15 \times 6 = 0.90$$
$$18 + 0.90 = 18.90 \text{ meters}$$
2.
Add the leftover material:
* Material used = 18.90 meters
* Material left over = 2.5 meters
* Total bought = Used + Leftover
Let's do the addition:
$$18.90 + 2.50$$
$$18 + 2 = 20$$
$$0.90 + 0.50 = 1.40$$
$$20 + 1.40 = 21.40 \text{ meters}$$
The calculation matches the red answer key visible on the worksheet ("21.4m").
Final Answer:
21.4 m
