Answer 1

Ответ:

Пошаговое объяснение:

1) 12:3 = 4

2) 3/8 - 1 = 0,375 - 1 = -0,625

3) 1/4 : 15/32 = 1/4 * 32/15 = 8/15

Answer 2

To solve the expression 12:3,3/8-1,1/4:15/32, we follow the order of operations (also known as PEMDAS/BODMAS). Here's the step-by-step solution:

Step 1: Simplify the division and multiplication. 12 ÷ 3 = 4

3/8 ÷ 1/4 = (3/8) × (4/1) = 3/2

15/32 ÷ 3/2 = (15/32) × (2/3) = 5/32

After simplifying the division and multiplication, the expression becomes:

4, 3/2 - 5/32

Step 2: Find a common denominator to subtract the fractions. The common denominator of 2 and 32 is 32.

Converting 3/2 to the same denominator: 3/2 = (3/2) × (16/16) = 48/32

The expression now becomes:

4, 48/32 - 5/32

Step 3: Subtract the fractions. 4 - 5/32 = (4 × 32/32) - 5/32 = 128/32 - 5/32 = 123/32

The final result of the expression 12:3,3/8-1,1/4:15/32 is 123/32.
