Answer:
5 : 23
Step-by-step explanation:
because in total there are 92 students ( 20 + 72)
so the answer would be out of 92 ( _ : 92 )
and so then you need to find out how many students ate chocolate ice cream which was 20
so it would be 20:92
but this answer could also be simplified by 4 or 2 and u would still get the same answer but I just used 2 so 2 goes into both of them so to simplify all u do is :
20 ÷ 2 = 10
92 ÷ 2 = 46
the answer would then be 10:46
but this can also be simplified again by 2:
10 ÷ 2 = 5
46 ÷ 2 = 23
So the last and final answer would be 5 : 23
Hope this helps and hopefully it's right, sorry if it's wrong though
