Here are five math word problems involving fractions, set in a superhero theme.

Problem 1: Captain Fraction's Power

Captain Fraction's power meter is currently at 3/4 of its maximum capacity. To defeat a villain, he must use 1/4 of his total power. What fraction of his power will be left after the battle?

Solution:

To find the remaining power, we need to subtract the power used from the current power level. Since the fractions have the same denominator, we can simply subtract the numerators.

$$3/4 - 1/4 = (3 - 1)/4 = 2/4$$

The fraction 2/4 can be simplified to 1/2. So, Captain Fraction will have 1/2 of his power left.


Problem 2: The Villain Capture Contest

Superheroes Bolt and Violet are in a contest to see who can capture more villains. There are a total of 8 villains. Bolt has captured 3/8 of the villains, and Violet has captured 4/8 of them. Who has captured more villains, and by what fraction?

Solution:

To compare the fractions, we can see that they have the same denominator. Therefore, we just compare the numerators.

4 is greater than 3, so 4/8 is greater than 3/8. Violet has captured more villains.

To find the difference, we subtract the smaller fraction from the larger one:

$$4/8 - 3/8 = (4 - 3)/8 = 1/8$$

Violet captured 1/8 more of the villains than Bolt.


Problem 3: Assembling the Mission Puzzle

A team of superheroes is working together to complete a mission that is represented by a puzzle. They have already completed 2/5 of the puzzle. Today, they complete another 1/5 of the puzzle. What fraction of the mission puzzle is now complete?

Solution:

To find the total fraction of the puzzle that is complete, we need to add the two fractions. Since they have the same denominator, we can simply add the numerators.

$$2/5 + 1/5 = (2 + 1)/5 = 3/5$$

The superhero team has now completed 3/5 of the mission puzzle.


Problem 4: The Energy Drain

Superhero Superman has an energy bar that is 7/8 full. A villain, Dr. Drain, uses a device to steal 1/4 of his total energy. What fraction of Superman's energy is left?

Solution:

To find the remaining energy, we must subtract the stolen energy fraction from the initial energy fraction. The fractions have different denominators (8 and 4).

First, we need to find a common denominator, which is 8.

We convert 1/4 to an equivalent fraction with a denominator of 8:

$$1/4 = (1 \times 2) / (4 \times 2) = 2/8$$

Now we can subtract the fractions:

$$7/8 - 2/8 = (7 - 2)/8 = 5/8$$

Superman has 5/8 of his energy left.


Problem 5: The Super Flight

A superhero can fly a total distance of 20 miles on a single charge. They fly for a while and cover 3/4 of this total distance. How many miles did the superhero fly?

Solution:

To find the distance flown, we need to multiply the total distance by the fraction.

$$3/4 \times 20 = (3 \times 20) / 4$$
$$= 60 / 4$$
$$= 15$$

The superhero flew 15 miles.
