Question

Kiara
7.38 − 5.71 = 0.29 + 1 + 0.38
= 1.67

Cho
7.38 − 5.71 = 0.39 + 0.62
= 1.01

Answer 1

Let's go through the calculations step by step for both Kiara and Cho.

**Kiara's Calculation:**
1. **Calculate \( 7.38 - 5.71 \)**:
\[
7.38 - 5.71 = 1.67
\]

2. **Calculate \( 0.29 + 1 + 0.38 \)**:
\[
0.29 + 1 = 1.29
\]
\[
1.29 + 0.38 = 1.67
\]

So, Kiara's calculations are correct:
\[
7.38 - 5.71 = 1.67
\]
\[
0.29 + 1 + 0.38 = 1.67
\]

**Cho's Calculation:**
1. **Calculate \( 7.38 - 5.71 \)**:
\[
7.38 - 5.71 = 1.67
\]

2. **Calculate \( 0.39 + 0.62 \)**:
\[
0.39 + 0.62 = 1.01
\]

Cho's calculations are also correct:
\[
7.38 - 5.71 = 1.67
\]
\[
0.39 + 0.62 = 1.01
\]

**Summary**:
- Kiara calculated \( 0.29 + 1 + 0.38 = 1.67\), and it equals \( 7.38 - 5.71 = 1.67\).
- Cho calculated \( 0.39 + 0.62 = 1.01\), which does not equal \( 7.38 - 5.71\).

Thus, both have their calculations noted correctly, but Cho's addition does not match the subtraction result.
