What is 1/2 + 3/4 because it is not 5/4

Hey!

Solution:

Find common denominators.

1/2 = 2/4

3/4 = 3/4

Add.

2/4 + 3/4 = 5/4

Simplify.

5/4 = 1 1/4

*Note* When you add or subtract fractions only add or subtract the numerators not the denominators.

1 1/4 or 1.25

Hope This Helped! Good Luck!

Step-by-step explanation: To add unlike fractions such as 1/2 + 3/4, first find a common denominator.

The common denominator of 2 and 4 is simply the least common multiple of 2 and 4 which is 4. To get 4 in the denominator of 1/2, we can multiply the numerator and denominator by 2 and we will get 2/4.

Notice that our second fraction already has 4 in the denominator so we can leave that how is it. Now, we can simply add our fractions together because they are like fractions meaning that they have the same denominator.

To add like fractions, we can simply add the numerators and keep the original denominator the same.

The answer would be 5/4 but we can change this into a mixed number. To write an improper fraction as a mixed number, divide the denominator into the numerator.

4 divides into 5 one time with a reminder of 1. Therefore, 5/4 can be written as the mixed number .

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
