Hi,

You are absolutely correct.

You need to write it in decimal form.

Here are the answers

19) 5/11 = 0.4545 (Repeating decimal)

20) 6/10 = 0.6  (terminating decimal)

21) 4/11 = 0.3636363  (Repeating decimal)

22) 10/15 = 0.666667  (Repeating decimal)

Thank you :)

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
