Question

0.17 + (0.68—0.17)* （20- -14.4)/-21.3- -14.4)

Answer 1

See the steps below

Explanation:

`0.17 + \cfrac{(0.68-0.17)(20- (-14.4))}{-21.3- (-14.4)} =`

`0.17 + \cfrac{0.51(20+14.4)}{-21.3+14.4} =`

`0.17 + \cfrac{0.51*34.4}{-6.9} =`

`0.17 - \cfrac{17.544}{6.9} =`

`\cfrac{17}{100} - \cfrac{17544}{6900} =`

`\cfrac{17*69-17544}{6900} =\\`

`-\cfrac{16371}{6900} =`

`-\cfrac{5457}{2300} =`

`-2\cfrac{857}{2300}`
