Answer 1

substitute the given values in the formula of (BAC) we have

`48\cdot3.2\colon160-3\cdot0.015`

Remember

Applying PEMDAS

P ----> Parentheses first

E -----> Exponents (Powers and Square Roots, etc.)

MD ----> Multiplication and Division (left-to-right)

AS ----> Addition and Subtraction (left-to-right)

so

step 1

solve the multiplication

48*3.2=153.6

substitute

`153.6\colon160-3\cdot0.015`

step 2

Solve the division

153.6/160=0.96

substitute

`0.96-3\cdot0.015`

step 3

solve the multiplication

3*0.015=0.045

substitute

`0.96-0.045`

step 4

solve the subtraction

0.96-0.045=0.915
