Mastering Decimal Word Problems: A Comprehensive Guide

Decimal word problems can be challenging, but with practice and a solid understanding of decimal operations, you can become proficient in solving them. In this article, we will provide you with 10 decimal word problems to test your skills, along with step-by-step solutions and explanations.

Problem 1: Shopping

Tom buys a shirt for 23.50 and a pair of pants for 17.25. How much does he pay in total?

Solution:

To find the total amount Tom pays, we need to add the cost of the shirt and the pants.

23.50 + 17.25 = $40.75

Therefore, Tom pays $40.75 in total.

Problem 2: Measurement

A water tank can hold 3.5 liters of water. If 2.8 liters of water are already in the tank, how much more water can be added?

Solution:

To find out how much more water can be added, we need to subtract the amount of water already in the tank from the total capacity.

3.5 liters - 2.8 liters = 0.7 liters

Therefore, 0.7 liters of water can be added to the tank.

Problem 3: Cooking

A recipe requires 2.25 cups of flour to make a cake. If you want to make half a cake, how much flour do you need?

Solution:

To find out how much flour is needed for half a cake, we need to multiply the amount of flour required for a full cake by 0.5.

2.25 cups × 0.5 = 1.125 cups

Therefore, you need 1.125 cups of flour to make half a cake.

Problem 4: Finance

A bank account has a balance of 456.78. If 275.90 is withdrawn, what is the new balance?

Solution:

To find the new balance, we need to subtract the amount withdrawn from the initial balance.

456.78 - 275.90 = $180.88

Therefore, the new balance is $180.88.

Problem 5: Science

A scientist measures the length of a specimen to be 5.62 centimeters. If the measurement is repeated and found to be 5.71 centimeters, what is the difference between the two measurements?

Solution:

To find the difference between the two measurements, we need to subtract the smaller measurement from the larger measurement.

5.71 cm - 5.62 cm = 0.09 cm

Therefore, the difference between the two measurements is 0.09 cm.

Problem 6: Transportation

A car travels 234.5 kilometers in 4 hours. How many kilometers does it travel per hour?

Solution:

To find out how many kilometers the car travels per hour, we need to divide the total distance traveled by the time taken.

234.5 km ÷ 4 hours = 58.625 km/h

Therefore, the car travels 58.625 kilometers per hour.

Problem 7: Shopping

A store offers a discount of 15% on a product that costs $85.99. How much will you pay for the product after the discount?

Solution:

To find the amount you will pay after the discount, we need to calculate 15% of the original price and subtract it from the original price.

15% of 85.99 = 0.15 × 85.99 = 12.8985 85.99 - 12.8985 = 73.0915

Therefore, you will pay $73.09 for the product after the discount.

Problem 8: Sports

A basketball player scores 23.5 points in the first half and 17.8 points in the second half. What is the player’s total score?

Solution:

To find the player’s total score, we need to add the points scored in the first half and the second half.

23.5 points + 17.8 points = 41.3 points

Therefore, the player’s total score is 41.3 points.

Problem 9: Health

A patient is prescribed 2.5 milligrams of medication per day. If the medication is taken twice a day, how much medication is taken in total?

Solution:

To find the total amount of medication taken, we need to multiply the amount taken per dose by the number of doses taken.

2.5 mg × 2 = 5 mg

Therefore, the patient takes 5 mg of medication in total.

Problem 10: Construction

A building has 5 floors, and each floor has 3.75 meters of corridor. What is the total length of corridor in the building?

Solution:

To find the total length of corridor, we need to multiply the length of corridor per floor by the number of floors.

3.75 m × 5 = 18.75 m

Therefore, the total length of corridor in the building is 18.75 meters.
