Answer 1

Hey there! :D

1. 7.6 repeating ____ 55 squared

Find 55 squared.

7.6 < 3025

7.6 is less than 7.4.

2. We already know we have 11 as the whole number.

When you have a repeating decimal, you can keep it as a fraction but use 99 as the denominator.

42/99 with the 11 whole number is the answer.

3. -31/6, -5, -5/6, -26^2 <== least to greatest.

-31/6= -5.16667 -26^2= 676

4. I think the 50 is the square root. Everything else can be represented as a fraction or ratio. The square root of 50 is irrational, and cannot be represented by a fraction or ratio. 50 squared is the one that doesn't belong.

I hope this helps!
