Answer 3

To calculate the result of the expression, simply follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).

The expression is: 10/30 * (-9/7)

Step 1: Perform the multiplication first.

10/30 * (-9/7) = (10 * -9) / (30 * 7)

Step 2: Simplify the numerator and denominator.

Numerator: 10 * -9 = -90 Denominator: 30 * 7 = 210

Step 3: Reduce the fraction (if possible).

The fraction -90/210 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD is 30.

-90 ÷ 30 = -3 210 ÷ 30 = 7

The simplified fraction is -3/7.

So, 10/30 * (-9/7) = -3/7.
