Answer:

LCD=280

Step-by-step explanation:

Equivalent Fractions with the LCD

1/8 = 35/280

2/7 = 80/280

4/5 = 224/280

Solution:

Rewriting input as fractions if necessary:  1/8, 2/7, 4/5

For the denominators (8, 7, 5) the least common multiple (LCM) is 280.

LCM(8, 7, 5)

Therefore, the least common denominator (LCD) is 280.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 35/35 = 35/280

2/7 = 2/7 × 40/40 = 80/280

4/5 = 4/5 × 56/56 = 224/280

<h2>Solution (a) :-</h2>

Let the cost of the less expensive comic book be x .

Then :-

1284 - 11x = x

Using this equation , we can find the cost of the less expensive comic book .

Price of the less expensive book :-

1284 - 11x = x

11x + x = 1284

12x = 1284

x =  \frac{1284}{12}

x = 107

Cost of the less expensive book is 107 .

Therefore , the epice of the less expensive book = $ 107 .

<h2>Solution (b) :-</h2>

Cost of the more expensive book = 11x

Which means :-

1284 - x = 11x

11x + x = 1284

12x = 1284

x = 107

11x = 11 \times 107

= 1177

Therefore , the price of the more expensive book = $ 1177 .
