Question

46,2 x 1,5 - (7,3-5 3/7) x (-70) Подробно,по действиям!

Answer 1

1 ) 46,2×1.5 = 69.3  2) 7.3- 5 3/7 = 1 61 /70  3)1 61/70 × (-70 )=-131  4) 69.3 -(-131)=131 + 69.3= 200.3

Answer 2

Sure, let's solve the expression step by step:

1. First, let's perform the operations inside the parentheses: (7.3 - 5 3/7) = (7.3 - 5.428571...) ≈ 1.871428... Note: 5 3/7 can be converted to a decimal by dividing 3 by 7 (approximately 0.428571...), then adding it to 5. This gives us 5.428571....

2. Now, let's multiply the value obtained in step 1 by -70: 1.871428... x (-70) ≈ -131.0 (Rounded to one decimal place)

3. Next, let's multiply the first two numbers in the expression: 46.2 x 1.5 = 69.3

4. Finally, subtract the result from step 2 from the result in step 3: 69.3 - (-131.0) = 69.3 + 131.0 = 200.3

So, the final result of the expression is approximately 200.3.
