Let's solve each of the decimal word problems step by step.

Problem 1:
Ashley is making cookies for her office’s Christmas party. Each batch of cookie mix needs 0.4 cups of sugar, and each batch can make 16 cookies. If Ashley is making 4 batches of cookies, how much sugar does she need?
####
Step-by-step solution:
- Sugar needed per batch = 0.4 cups
- Number of batches = 4
- Total sugar needed = 0.4 cups × 4
$$
0.4 \times 4 = 1.6 \text{ cups}
$$
✔ Answer: Ashley needs
1.6 cups of sugar.

Problem 2:
Ashley found 2 boxes of sugar in the kitchen. The green box is 1.26 kg, and the red box is 1.028 kg. Which box contains more sugar?
####
Step-by-step solution:
We compare the two weights:
- Green box: 1.26 kg
- Red box: 1.028 kg
To compare decimals, align them by place value:
```
1.260
- 1.028
```
Now compare digit by digit:
- Ones place: both have 1 → equal
- Tenths place: 2 vs 0 → 2 > 0
So,
1.260 > 1.028
✔ Answer: The
green box contains more sugar.

Problem 3:
Ashley measured 1.43 cups of sugar. How much more sugar does she need?
Wait — this problem seems incomplete. It says she measured 1.43 cups, but we don't know
how much total sugar she needs to determine how much more she needs.
But let’s look back at
Problem 1: She needs
1.6 cups total for 4 batches.
So if she already has
1.43 cups, then:
$$
\text{More sugar needed} = 1.6 - 1.43 = ?
$$
Subtract:
$$
1.60 - 1.43 = 0.17 \text{ cups}
$$
✔ Answer: Ashley needs
0.17 more cups of sugar.
---
✔ Final Answers:
1.
1.6 cups of sugar
2. The
green box has more sugar
3.
0.17 cups more sugar needed
