Christina estimated 188% of 91 by performing these steps. What did she do wrong?
(90)(190%)
= (90)(100%+90%)
= (90)(100%) +(90) (90%)
= (90)(1.0)+(90) (0.9)
= 90+ 18
= 108
2 pretty major mistakes, the numbers are messed up in her calculations. If she had done the correct numbers although her way of solving is not the best way, she would have gotten the correct answer
