Answer 1

$= \frac{11}{20}- \frac{13}{30} = \frac{33}{60}- \frac{26}{60}= \frac{33-26}{60}= \frac{7}{60} \\ \frac{7}{60} * \frac{9}{14}= \frac{1}{20} * \frac{3}{2}= \frac{3}{40}$

Answer 2

To solve the expression (11/20 - 13/30) × 9/14, we can follow these steps:

Step 1: Simplify the expression within the parentheses. To subtract fractions, we need to have a common denominator. In this case, the common denominator for 20 and 30 is 60.

(11/20 - 13/30) = (33/60 - 26/60) = 7/60

Step 2: Multiply the result from step 1 by 9/14. To multiply fractions, we simply multiply the numerators and denominators.

(7/60) × (9/14) = (7 × 9) / (60 × 14) = 63/840

Therefore, the value of the expression (11/20 - 13/30) × 9/14 is 63/840.
