Question

(2.7-1/5):(1/2+4.5)=

Answer 1

(2,7 - 1/5) : (1/2 + 4,5) = (2,7 - 0,2) : (0,5 + 4,5) = 2,5 : 5 = 2,5 * 1/5 = 0,5

Answer 2

$(2.7 - \frac{1}{5} ) \div ( \frac{1}{2} + 4.5) =$
$= (2 \frac{7}{10} - \frac{2}{10} ) \div ( \frac{1}{2} + 4 \frac{1}{2} ) =$
$= (2 \frac{1}{2} ) \div5 =$
$= 2.5 \div 5 = 2$

Answer 3

To simplify the expression (2.7 - 1/5) : (1/2 + 4.5), we need to perform the operations step by step.

Step 1: Calculate the values inside the parentheses (1/2 + 4.5): 1/2 + 4.5 = (1/2) + (9/2) = 10/2 = 5

Step 2: Calculate the division (2.7 - 1/5) : 5: 2.7 - 1/5 = 2.7 - 0.2 = 2.5

Therefore, (2.7 - 1/5) : (1/2 + 4.5) = 2.5 : 5 = 0.5
