@justuu

OpenStudy (haleyelizabeth2017):

to make it easier, use \(\Large\frac{ 19 }{ 10 } \) instead of \(\Large{1\frac{ 9 }{ 10 }}\)

OpenStudy (haleyelizabeth2017):

so what is 19*12?

OpenStudy (anonymous):

I think it 228

OpenStudy (justuu):

correct

OpenStudy (haleyelizabeth2017):

correct. And so what is 228/10?

OpenStudy (anonymous):

um...

OpenStudy (haleyelizabeth2017):

Just move the decimal put in 228. one place to the left

OpenStudy (haleyelizabeth2017):

Okay I will give it to you. It is 22.8. Next, what I would do is do 22*10 to get 220 and then find how much is left (8)

OpenStudy (anonymous):

@justuu the possable answers are... A. 22 4/5 B. 12 9/10 C. 10 4/5 D. 19/120

OpenStudy (haleyelizabeth2017):

so the answer will be 22 4/5
