Пошаговое объяснение:

6 8/15-1,35=98/15-135/100=1960/300-405/300=1555/300=311/60=5 11/60

2 4/5+0,2=2 4/5+2/10=2+8/10+2/10=3

5 11/60:3=311/60*1/3=311/180=1 131/180

Answer 3

To calculate the expression (6 8/15 - 1.35) / (2 4/5 + 0.2), follow these steps:

1. Convert mixed numbers to improper fractions:

6 8/15 = (6 * 15 + 8) / 15 = (90 + 8) / 15 = 98/15

2 4/5 = (2 * 5 + 4) / 5 = (10 + 4) / 5 = 14/5

2. Now, rewrite the expression with these fractions:

(98/15 - 1.35) / (14/5 + 0.2)

3. Perform the subtraction and addition within the parentheses:

(98/15 - 1.35) = (98/15 - 135/100) = (392/60 - 81/60) = (311/60)

(14/5 + 0.2) = (14/5 + 1/5) = (15/5)

4. Rewrite the expression:

(311/60) / (15/5)

5. To divide by a fraction, multiply by its reciprocal:

(311/60) * (5/15)

6. Simplify the fractions:

(311/60) * (1/3) = (311/180)

So, the value of the expression is 311/180.
