1.
Find the approximate result of the following
expression (in whole numbers) :
49.0 X 10.2 – 7.1 x 29,7 -5.1 x 20,1​

Answer 1

The approximate value is 186

Step-by-step explanation:

we have to solve the expression  

49.0 X 10.2 – 7.1 x 29.7 -5.1 x 20.1​

= (49.0 X 10.2 )-(7.1 x 29.7)-(5.1 x 20.1​)

= (499.8)-(210.87)-(102.51)

= (499.8)-(313.38)

= 186.42

the approximate value is 186

hence,

the value of the expression 49.0 X 10.2 – 7.1 x 29.7 -5.1 x 20.1​ = 186.42
