Find the decimal equivalent to 5 8/20

5.4

Step-by-step explanation:

To find its equivalent decimal, solve.

Step 1: Simplify the fraction

It seems like 2 can go into 20 and 8.

So, 20 ÷ 2 = 10, and 8 ÷ 2 = 4. Then we have:

, which can still be simplified further. So, by 2:

4 ÷ 2 = 2

10 ÷ 2 = 5

The final result is

Now we have . Since we already have a whole number (5), we can just convert the fraction () into a decimal.

Step 1: Solve

2 ÷ 5 = 0.4

However, we have 5, so the decimal equivalent to is

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
