Answer 2

To solve the expression 75/91 * 27/50 + 75/91 * 23/50, we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. Multiply the fractions: 75/91 * 27/50 and 75/91 * 23/50.

To multiply fractions, we multiply the numerators together and the denominators together. The result is a new fraction.

For the first multiplication, we have: 75/91 * 27/50 = (75 * 27) / (91 * 50).

For the second multiplication, we have: 75/91 * 23/50 = (75 * 23) / (91 * 50).

2. Add the two fractions together: (75 * 27) / (91 * 50) + (75 * 23) / (91 * 50).

Since the denominators are the same, we can add the numerators together and keep the denominator the same.

The expression simplifies to: (75 * 27 + 75 * 23) / (91 * 50).

Now, let's calculate the numerator and denominator separately:

Numerator: 75 * 27 + 75 * 23 = 2025 + 1725 = 3750.

Denominator: 91 * 50 = 4550.

Therefore, the expression simplifies to: 3750 / 4550.

To further simplify the fraction, we can find the greatest common divisor (GCD) of the numerator and denominator and divide both by it.

The GCD of 3750 and 4550 is 250.

Dividing both the numerator and denominator by 250, we get: (3750 / 250) / (4550 / 250) = 15 / 18.

The final simplified expression is 15/18.

So, the answer to the expression 75/91 * 27/50 + 75/91 * 23/50 is 15/18.
