2 2/4
1 3/4
3 1/4
Divide 9 by 4 to get 2 with a remainder of 1. This remainder over 4 gives the mixed number 2 1/4.
What is the area of a rectangle with length 3/5 and width 2/3?
2/5
6/15
1/2
3/5
Multiply the length and width: (3/5) × (2/3) = 6/15, which simplifies to 2/5. This simplified fraction represents the area of the rectangle.
Express the decimal 0.75 as a simplified fraction.
3/4
75/100
7/4
4/3
The decimal 0.75 can be written as 75/100, which simplifies to 3/4 after dividing the numerator and denominator by 25. Therefore, 3/4 is the simplified fraction.
Solve the addition: 2/3 + 3/10.
29/30
25/30
1
5/6
Find a common denominator for 2/3 and 3/10, which is 30. Converting gives 20/30 and 9/30; their sum is 29/30. This is the correct answer after performing the addition.
If a/b = 3/4 and b/c = 2/5, what is a/c?
3/10
6/9
1/2
3/8
To find a/c, multiply the two given fractions: (3/4) × (2/5) = 6/20, which simplifies to 3/10 after dividing numerator and denominator by 2.
Solve for x in the equation: 1/3 + x = 5/6.
1/2
1/3
3/4
2/3
Subtract 1/3 from both sides of the equation. Converting 1/3 to 2/6 allows you to compute 5/6 - 2/6 = 3/6, which simplifies to 1/2, the correct value of x.
A piece of ribbon is 7/8 yard long. If you cut it into 3 equal pieces, what is the length of each piece?
7/24
7/21
1/3
3/8
Dividing the total length by 3 is equivalent to multiplying 7/8 by 1/3, which results in 7/24. This represents the length of each of the three equal pieces.
How many times does the fraction 1/8 fit into 3/4?
6
5
7
8
Dividing 3/4 by 1/8 determines how many 1/8 units are in 3/4. This calculation yields (3/4) ÷ (1/8) = (3/4) × 8 = 6, so 1/8 fits into 3/4 six times.
Simplify the expression: (3/4 - 1/3) / (2/3 + 1/6).
1/2
5/12
5/6
1/3
First, simplify the numerator: 3/4 - 1/3 = 9/12 - 4/12 = 5/12. Next, simplify the denominator: 2/3 + 1/6 = 4/6 + 1/6 = 5/6. Dividing (5/12) by (5/6) gives (5/12) × (6/5) = 1/2.

Quiz: Each Parent Contributes in Sexual Reproduction Cheat Sheet

  1. Fraction Fundamentals - Fractions break whole things into equal parts, with the numerator showing how many parts you have and the denominator showing the total slices. It's like pizza: the more slices you take, the larger your share! Grasping this tasty concept is your first step to fraction mastery. SplashLearn: Fraction Basics
  2. Same Denominator Addition & Subtraction - When denominators match, math becomes a breeze: just add or subtract the numerators and keep the bottom number unchanged. For example, 1/4 + 2/4 = 3/4 - simple and satisfying! Use this trick to solve many fraction problems faster. GCFLearnFree: Adding & Subtracting Fractions
  3. Unlike Denominator Magic - Different denominators? No problem! Find the least common denominator (LCD), convert each fraction to that LCD, then combine the numerators. It's like finding a common language so fractions can "speak" together. LibreTexts: Unlike Denominator Fractions
  4. Multiplying Fractions - To multiply fractions, pair up the numerators and denominators separately: multiply tops together and bottoms together. For instance, 2/3 × 3/4 = 6/12, which simplifies to 1/2. It's a straight path - no common denominator needed! SplashLearn: Fraction Rules
  5. Dividing Fractions - Division means flipping! Take the reciprocal of the second fraction and then multiply. So 2/3 ÷ 3/4 becomes 2/3 × 4/3 = 8/9. It's like turning a door knob - flip then go through! SplashLearn: Fraction Rules
  6. Mixed & Improper Conversion - Mixed numbers combine a whole and a fraction; improper fractions have a larger numerator. To switch to improper, multiply the whole by the denominator, add the numerator, and keep the same bottom number. It's just a quick number dance! SplashLearn: Fraction Rules
  7. Simplifying Fractions - Shrink fractions to their simplest form by dividing both numerator and denominator by their greatest common divisor (GCD). For example, 8/12 ÷ 4/4 turns into 2/3. It's like folding a paper until it's as small as possible! SplashLearn: Simplifying Fractions
  8. Comparing Fractions - With the same denominator, the larger numerator wins. If they differ, convert to a common denominator or change to decimals. It's like comparing two pizza slices by making sure they're cut the same way! SplashLearn: Fraction Rules
  9. Equivalent Fractions - Multiplying or dividing top and bottom by the same number gives an equivalent fraction. For example, 1/2 = 2/4 = 3/6. Think of it as dressing the same pizza slice in different-sized boxes - it's still the same slice inside! SplashLearn: Equivalent Fractions
  10. Practice Power-Up - The secret ingredient to fraction success is practice. Tackle a variety of problems, celebrate your wins, and learn from mistakes - they're just hidden lessons in disguise. Keep going and watch your fraction confidence skyrocket! SplashLearn: Practice Worksheets
