Question

14-13,2:(3 11/21- 2 4/15)=

Answer 1

3 11/21- 2 4/15=74/21-34/15=370/105-238/105=132/105
13.2:132/105=66/5*105/132=21/2=10.5
14-10.5=3.5

Answer 2

3 11/21- 2 4/15=74/21-34/15=370/105-238/105=132/105
13.2:132/105=66/5*105/132=21/2=10.5
14-10.5=3.5

Answer 3

To solve the expression you provided, let's break it down step by step:

1. Subtract 2 from 14: 14 - 2 = 12

2. Next, subtract 13 from 12: 12 - 13 = -1

3. Now, let's convert the fractions to a common denominator. The denominators are 2 and 15, so the common denominator is 30.

   For 3 11/21: 3 * 21 = 63 63 + 11 = 74 So, 3 11/21 is equal to 74/21.

   For 2 4/15: 2 * 15 = 30 30 + 4 = 34 So, 2 4/15 is equal to 34/15.

4. Subtract the fractions: (74/21) - (34/15)

   To subtract fractions, we need to have a common denominator, which is 21 * 15 = 315.

   (74/21) * (15/15) = 1110/315 (34/15) * (21/21) = 714/315

5. Now, we can subtract the fractions: (1110/315) - (714/315) = 396/315

6. Reduce the fraction to its simplest form: 396/315 = 4/3

Finally, the result of the expression is 4/3.
