TEKS 4.2H Worksheets — Grade 4 Determine the corresponding decimal to the tenths

Sofia went to the Texas State Fair and bought 2 corn dogs for $3.50 each and 1 funnel cake for $4.75. How much did Sofia spend in total?

1. $11.75 ✓
2. $12.25
3. $10.50
4. $13.00

Why: To find the total amount Sofia spent, first calculate the cost of the corn dogs: 2 corn dogs × $3.50 = $7.00. Then, add the cost of the funnel cake: $7.00 + $4.75 = $11.75. Therefore, Sofia spent a total of $11.75.

Maurice is planting a garden in his backyard in Texas. He has a number line to help him measure the distance between his rows. If his first row is at 0.0 meters and his second row is at 0.4 meters, what decimal represents the distance of the second row from the start on the number line?

1. 0.4 ✓
2. 0.44
3. 0.54
4. 0.34

Why: To determine the distance of the second row from the start on the number line, you look at the marked point for the second row, which is at 0.4 meters. Thus, the correct decimal representation is 0.4.

Daniel is planting a vegetable garden in his backyard in Texas. He has a number line where each point represents the depth in inches he will plant his seeds. The number line goes from 0 to 2 inches and is marked at 0.5, 1.0, and 1.5 inches. Daniel decides to plant the seeds at the point that corresponds to 1.3 inches on the number line. What decimal represents the depth of the seeds Daniel has planted?

1. 1.3 ✓
2. 1.5
3. 0.3
4. 1.0

Why: Daniel planted his seeds at the point that corresponds to 1.3 inches on the number line. Therefore, the decimal representing the depth of the seeds is 1.3. This means that the correct answer is 1.3.

Faris went to Big Bend National Park and measured the heights of various cacti along a trail. The heights of the cacti in meters are represented on a number line. One cactus is located at 2.4 meters on the number line. What is the value of the cactus's height in tenths of a meter?

1. 24 ✓
2. 2.4
3. 2
4. 20

Why: To find the height of the cactus in tenths of a meter, multiply the decimal 2.4 by 10. This gives us 2.4 * 10 = 24 tenths. This is a common misunderstanding, as some students may confuse the decimal representation with whole numbers. Remember, 2.4 meters equals 24 tenths of a meter.

Amir is visiting the Texas State Fair in Dallas. He buys 2 cotton candies for $2.50 each and a funnel cake for $5.00. How much money did Amir spend in total?

1. $10.00 ✓
2. $8.00
3. $7.50
4. $6.50

Why: To find the total amount Amir spent, you first calculate the cost of the cotton candies: 2 cotton candies × $2.50 each = $5.00. Then, add the cost of the funnel cake: $5.00 + $5.00 = $10.00. Therefore, Amir spent a total of $10.00.

Santiago is measuring the depth of Galveston Bay at various points. He marks a point on the number line at 0.7 meters. Which decimal represents the depth of the water at that point in the tenths place?

1. 0.7 ✓
2. 0.6
3. 0.8
4. 0.5

Why: The point marked at 0.7 meters represents a depth of 7 tenths. In a decimal, this is shown as 0.7, where the digit 7 is in the tenths place, meaning there are seven tenths of a meter of water at that point.

Andrea is measuring the height of a cactus in the desert near Austin, Texas. She finds that the cactus is about 2.4 meters tall. Which point on the number line best represents the height of the cactus in decimal form?

1. 2.4 ✓
2. 2.14
3. 2.5
4. 2.34

Why: The height of the cactus is given as 2.4 meters. When looking for the corresponding decimal point on the number line, 2.4 is the precise representation of its height. The other options either round the number or are incorrect decimals, making 2.4 the correct answer.

Ximena visited Padre Island National Seashore and recorded the temperatures throughout the day. In the morning, the temperature was 25.4 degrees Celsius, and in the afternoon, it increased by 3.6 degrees Celsius. What was the afternoon temperature?

1. 29.0 ✓
2. 28.8
3. 31.0
4. 25.8

Why: To find the afternoon temperature, add the increase of 3.6 degrees Celsius to the morning temperature of 25.4 degrees Celsius. So, 25.4 + 3.6 = 29.0 degrees Celsius. Therefore, the correct answer is 29.0.
