Let’s solve each problem one by one. These are all multiplication word problems — we just need to multiply the original amount by how many times they want to make it.

Problem 1:
Chef Anna used 0.75 pounds of potatoes. She needs to make 4.2 times that amount.
→ Multiply: 0.75 × 4.2
Let’s calculate:
0.75 × 4 = 3.00
0.75 × 0.2 = 0.15
Add them: 3.00 + 0.15 =
3.15
✔ Answer: 3.15 pounds

Problem 2:
Recipe calls for 0.6 cups of sugar. Chef John wants 2.5 times that.
→ Multiply: 0.6 × 2.5
0.6 × 2 = 1.2
0.6 × 0.5 = 0.3
Add: 1.2 + 0.3 =
1.5
✔ Answer: 1.5 cups

Problem 3:
Chef Lisa uses 0.8 ounces of spices. Needs 3.7 times that.
→ Multiply: 0.8 × 3.7
Break it down:
0.8 × 3 = 2.4
0.8 × 0.7 = 0.56
Add: 2.4 + 0.56 =
2.96
✔ Answer: 2.96 ounces

Problem 4:
Recipe requires 0.4 liters of milk. Chef Mike wants 3.2 times that.
→ Multiply: 0.4 × 3.2
0.4 × 3 = 1.2
0.4 × 0.2 = 0.08
Add: 1.2 + 0.08 =
1.28
✔ Answer: 1.28 liters

Problem 5:
Chef Emma uses 0.9 pounds of flour. Needs 2.8 times that.
→ Multiply: 0.9 × 2.8
0.9 × 2 = 1.8
0.9 × 0.8 = 0.72
Add: 1.8 + 0.72 =
2.52
✔ Answer: 2.52 pounds
---
Problem 6:
Recipe requires 0.7 cups of oil. Chef Sam wants 4.5 times that.
→ Multiply: 0.7 × 4.5
0.7 × 4 = 2.8
0.7 × 0.5 = 0.35
Add: 2.8 + 0.35 =
3.15
✔ Answer: 3.15 cups

Problem 7:
Chef Olivia uses 0.5 ounces of yeast. Needs 3.6 times that.
→ Multiply: 0.5 × 3.6
0.5 × 3 = 1.5
0.5 × 0.6 = 0.3
Add: 1.5 + 0.3 =
1.8
✔ Answer: 1.8 ounces
