15/28 + 5/28 = (15 + 5)/28 = 20/28 = 5/7 after simplifying by dividing numerator and denominator by 4.

2/3 × 1/2 = 2/6 = 1/3 cup.

3/4 × 7 = 21/4 = 5.25 km.

Half of 5/6 = 5/6 × 1/2 = 5/12.

3/4 ÷ 1/8 = (3/4 × 8/1) = 24/4 = 6 pieces.

Five-eighteenths is written as a fraction where the numerator is 5 and the denominator is 18, which is 5/18. Therefore, the correct answer is option C.

2/5 × 200 = 80 kg.

Multiply numerators 2 × 4 = 8 and denominators 3 × 5 = 15.

7/12 × 6/7 = 42/84 = 1/2.

To simplify ,we convert the division into a multiplication by the reciprocal: 

We then find common factors to simplify:

• 13and 39 share the factor 13, so 39 simplifies to 3.
• 18 and 36 share the factor 18, so 36 simplifies to 2.

After simplifying, the fraction becomes:

2/3 ÷ 1/9 = 2/3 × 9/1 = 18/3 = 6 glasses.

Division = multiply by reciprocal: 9/10 × 5/3 = 45/30 = 3/2.

Multiply numerators and denominators:
5 × 16 = 80
8 × 25 = 200,
So the product is 80/200.

Simplify 80/200 by dividing numerator and denominator by 40:
80 ÷ 40 = 2, 200 ÷ 40 = 5.

Final answer: 2/5, therefore option A is correct.

Step 1: Apply the invert-and-multiply rule:11/15 ÷ 22/45 = 11/15 × 45/22.

Step 2: Cancel common factors before multiplying:11 and 22 have a common factor of 11, so 11/22 = 1/2;15 and 45 have a common factor of 15, so 45/15 = 3/1.This reduces the expression to 1/1 × 3/2.

Step 3: Multiply the numerators and denominators:(1 × 3)/(1 × 2) = 3/2.

Therefore, 11/15 ÷ 22/45 = 3/2.
