timofeeve [1]
So, first we input 6
24 - 6 = 18
So we now need to find the square root of 18
If you're allowed to use a calculator, the square root is 4.242

What is 1 7/8 Times 2 1\3
slamgirl [31]
We need to convert the mixed fractions into improper fractions.

1*8 = 8 
8+7 = 15

15/8 

2*3 = 6
6+1 = 7

7/3

Now we can finish and multiply

\frac{15*7}{8*3}

15*7 = 105
8*3 = 24

Simplify 105/24

105/24

24*4 = 96

105 - 96 = 9

4 is the whole number, and 9 is the numerator.

4  9/24

Simplify that,

9/3 = 3
24/3 = 8

4  3/8

Answer: 4\frac{3}{8}
