Question

Mei is writing 4.28 as a mixed number. Find her mistake.

Mei's work:
4.28=4 28/1,000
or 4 7/250.

Answer 1

Step-by-step explanation:Her mistake is that she put 28 over 1,000 as if it was in the thousands place when she should have put it over 100 because it is in the hundreths place. The correct answer is 4 7/25

Answer 2

`4.28=4+0.28=4+(28)/(100)=4+(28:4)/(100:4)=4+(7)/(25)=\boxed{\boxed{4(7)/(25)}}`
