в) 7/1-6,2=0,8

г) 915--1,8=916,8

Answer 2

Calculation of Expressions:

a) 2.4 + 1/2

To calculate this expression, we add 2.4 to the result of dividing 1 by 2.

Solution: 2.4 + 1/2 = 2.4 + 0.5 = 2.9

b) 3.7 - 2

To calculate this expression, we subtract 2 from 3.7.

Solution: 3.7 - 2 = 1.7

c) 7/1 - 6.2

To calculate this expression, we subtract 6.2 from the result of dividing 7 by 1.

Solution: 7/1 - 6.2 = 7 - 6.2 = 0.8

d) 915 - 1.8

To calculate this expression, we subtract 1.8 from 915.

Solution: 915 - 1.8 = 913.2

Therefore, the solutions to the given expressions are: a) 2.9 b) 1.7 c) 0.8 d) 913.2
