Answer 1

3/16*8/5=3/10 .. 15/2*1/10-3/5=15/20-3/5=3/20 .. 7/2 / 14/3=3/4 подставляем полученное 3/10/(3/20)-3/4=2-3/4=1.25

Answer 2

Solving the Expression

To solve the given expression, we can follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Step 1: Solve the expression inside the parentheses First, we solve the expression inside the parentheses: 3/16 * 8/5 : (15/2 * 1/10 - 3/5) - 7/2 : 14/3

Step 2: Perform the division and multiplication operations Next, we perform the division and multiplication operations from left to right.

3/16 * 8/5 = 24/80 15/2 * 1/10 = 15/20 7/2 : 14/3 = 21/28

Now, the expression becomes: 24/80 : 15/20 - 3/5 - 21/28

Step 3: Perform the subtraction and division operations Finally, we perform the subtraction and division operations from left to right.

24/80 : 15/20 = 6/80 6/80 - 3/5 = -69/80 -69/80 - 21/28 = -207/280 - 165/280 = -372/280 = -93/70

Solution

Therefore, the solution to the given expression 3/16 * 8/5 : (15/2 * 1/10 - 3/5) - 7/2 : 14/3 is -93/70.
