Question

equation by filling in the missing number.
9.) 2.9 - ______ = 1.4
10.) 3.4 - ______ = 2.9
11.) ______ - 3.7 = 2.2
12.) 8.5 - ______ = 4.3
13.) ______ - 0.8 = 3.6
14.) 7.2 - ______ = 5.5
15.) ______ - 4.1 = 2.9
16.) 9.6 - ______ = 8.2

Explanation:

Problem 9:

Step1: Let the missing number be \( x \). The equation is \( 2.9 - x = 1.4 \). To find \( x \), we rearrange the equation as \( x = 2.9 - 1.4 \).

\( x = 2.9 - 1.4 \)

Step2: Calculate the subtraction.

\( x = 1.5 \)

Step1: Let the missing number be \( x \). The equation is \( 3.4 - x = 2.9 \). Rearrange to \( x = 3.4 - 2.9 \).

\( x = 3.4 - 2.9 \)

Step2: Perform the subtraction.

\( x = 0.5 \)

Step1: Let the missing number be \( x \). The equation is \( x - 3.7 = 2.2 \). Rearrange to \( x = 2.2 + 3.7 \).

\( x = 2.2 + 3.7 \)

Step2: Add the numbers.

\( x = 5.9 \)

Answer:

\( 1.5 \)
