Question

Using fraction bars and decimal powers

Answer 1

2.4

Explanation:

Evaluating
`(16.8 - 1.2^2)/(-4.3 + 3(-0.7))`

`= (16.8 - 1.44)/(-4.3 + (-2.1))`

`= (15.36)/(-4.3 - 2.1))`

`= (15.36)/(-6.4))`

`= (15.36*10^2))/(-6.4*10^2))` (multiplying the numerator and denominator by 100)

`= (1536)/(640))`

`= 2.4`
