5/6 × 6 = 5 so 5/6 times 12= 10
Can you be more specific? I need a question and I need a close up ! Lol but I’m trying to help.
The answer of x=7, because 7+2=9
868 is about 870, and 28 is about 30, so your expression would be 870 divided by 30 which would be 29 and the actual answer is 31, so your estimate would be close to your actual answer.
