Answer 2

1/4 + 1/3 us LCD =12

= 3/12 +4/12 = 7/12

or in decimal form

1/4+1/3 = .25 +.333... = .58333...which also = 7/12

let x = .58333. and 10x = 5.8333..

10x-x = 5.8333..- .58333

9x = 5.25

x = 5.25/9 = 21/36= 7/12

Answer 3

Key Point for Solving Similar Problems:

Always find the least common denominator (LCD) of the fractions, convert each fraction to have that denominator, and then add or subtract the numerators. Keep the denominator the same.

Step 1: Find a common denominator.

The denominators are 4 and 3. The least common denominator (LCD) is 12.

Step 2: Convert each fraction to have the common denominator.

1/4 = 1*3 / 4*3 = 4/12

1/3 = 1*4 / 3*4 = 3/12

Step 3: Add the new fractions.

4/12+3/12 = 7/12

Answer 4

To solve 1/4 + 1/3, we need a common denominator (the bottom numbers of the fractions have to be the same). We can only add or subtract fractions with common denominators.

To make the bottom numbers the same for both fractions, we need to find the least common multiple of 4 and 3. A number that both 4 and 3 go into is 12.

Next, we work individually with each fraction and convert the fractions:

1. 1/4 = 3/12 (multiply numerator and denominator by 3)
2. 1/3 = 4/12 (multiply numerator and denominator by 4)

To add fractions, we keep the denominator the same and add the 2 numerators.

3/12 + 4/12 = 7/12

The fraction 7/12 is in its simplest form since 7 and 12 have no common factors other than 1.

Answer: 7/12

Answer 5

✅ Step 1: Find a common denominator

1. The denominators are 4 and 3.
2. A common denominator is 12 (the least common multiple of 4 and 3).

The way I know this is I look for a larger number that both 4 and 3 can go into .

I can write out multiples of 3 : 3,6,9, 12, 15

I can write out multiples of 4 : 4,8,12,16

I see that both have a multiple 12.

✅ Step 2: Change both fractions to have a denominator of 12

1. 1/4 = 3/12 (because 1 × 3 = 3 and 4 × 3 = 12)
2. 1/3 = 4/12 (because 1 × 4 = 4 and 3 × 4 = 12)

✅ Step 3: Add the new fractions

3/12 + 4/12 = 7/12

✅ Final Answer:

1/4 + 1/3 = 7/12
