Answer 2

Пошаговое объяснение:

1)3/8×2/5 : 3/16 =4/5

3/8×2/5×3/16=2/0

2/5×2=4/5

4/5, либо 0.8

2)1/6 + 17/18 - 2/3= 4/9

Answer 3

Let's solve the expression step by step:

1. 3/8 × 2/5: Multiply the fractions: (3/8) × (2/5) = 6/40 = 3/20

2. 1/6 + 17/18: Find a common denominator, which is 18 in this case: (1/6) + (17/18) = (3/18) + (17/18) = 20/18 = 10/9

3. 3/16 - 2/3: Find a common denominator, which is 48 in this case: (3/16) - (2/3) = (9/48) - (32/48) = -23/48

Now, let's put it all together:

3/20 : 10/9 + (-23/48)

To simplify the expression, first invert and multiply when dividing by a fraction:

3/20 × 9/10 + (-23/48)

27/200 - 23/48

To subtract these fractions, find a common denominator, which is 2400:

(27/200) × (12/12) - (23/48) × (50/50) 324/2400 - 1150/2400

Combine the fractions:

(324 - 1150)/2400 = -826/2400

Reduce the fraction:

-826/2400 = -137/400

So, the final result of the expression is -137/400.
