Question

18,6 : три четвертых - 14,4 * пять двенадцатых __________________________; 47,52 : 1,8 - 17

Answer 1

18,6:0,75 (три четвертых) - 14,4 *5 =-47,2

1) 18,6:0,75 = 24,8

2) 14,4 *5 = 72

3) 24,8 - 72 = -47,2

 

47,52 : 1,8 - 17 = 9,4

1) 47,52 : 1,8 = 26,4

2) 26,4 - 17 = 9,4

Answer 2

To solve the expression, let's break it down step by step.

1. Simplify the first part of the expression: 18.6 : (3/4) - (14.4 * 5/12)

2. Calculate the values inside the parentheses: 18.6 : (3/4) = 18.6 * (4/3) = 24.8

3. Now, simplify the second part of the expression: (14.4 * 5/12) = 7.2

4. Substitute the simplified values back into the expression: 24.8 - 7.2 = 17.6

Therefore, the value of the expression 18.6 : (3/4) - (14.4 * 5/12) is 17.6.

Now, let's move on to the second part of the expression:

1. Simplify the expression: 47.52 : 1.8 - 17

2. Perform the division: 47.52 : 1.8 = 26.4

3. Substitute the simplified values back into the expression: 26.4 - 17 = 9.4

Therefore, the value of the expression 47.52 : 1.8 - 17 is 9.4.
