Help please with these:
liq [111]

Answer:

18/36 in simplest form is 1/2.

1 5/8 to an improper fraction is 13/8

19/5 to mixed fraction is 3 4/5 in simplest form

Step-by-step explanation:

18 and 36 in share a common denominator of 18. 18 divided on 18 is 1. 36 divided on 18 is 2. so 1/2 is equivalent to 18/36.

1 5/8 equals one whole (8) plus 5. 8 + 5= 13. 13/5 is your answer

19 divided on 5 is 3.8. 3.8 converted to a fraction is 3 and 0.75. 0.75 in fraction form is 4/5. your answer is 19/5 = 3 4/5 or 3 and 8/10.

If this was correct then mark as brainliest.
