10 lbs/$12= 1 lb/x dollars.
If you rewrite it up and down and not slanted, it would be clearer to understand, but anyways, you cross multiply:
12*1=12
12/10= 1.2
So the answer is 1.2, if you put it on that bubble sheet, put 1, then a decimal, after the decimal 2, and then all 0's,.
2 to the first is 2 because there is only one 2
1 thousand and 1 hundred means 1100.
In scientific notation, it's 1.1*10^3
97/2 = 48.5
take the whole number below and above that
48 + 49 = 97
I would say 200,00 because if you see it like a roller coaster
down 1234
up 6789
Hope I helped ;-)
