Answer:
0.53
Step-by-step explanation:
0.533
Decimal places go 10ths, 100ths, 1000ths, and so on. The nearest hundred therefore, is the first 3. Looking at the next digit, which is 3, because it's less than 4, we know we have to round down, which makes the answer 0.53
2/5, because 2/5 is bigger than 0.25.
I'M SORRY I GOT IT WRONG
square root of 121 is11
square root of x^2 is x
so 11x
