Answer:
7.57
Explanation:
the order of decimal digits goes (left to right):
tenths, hundredths, thousandths
7 ones
5 tenths
7 hundredths
4 thousandths
since 4 is less than 5, you would keep the 7 otherwise rounding up to an 8, only if the thousandths place was equal to or greater than 5.
Hope this helped!!
