The simplest ratio is 1/3. Equivalent ratios would be 3/9 and 5/15.
Answer: 15
REMEMBER: The mode is the value that appears most frequently in a data set.
Yes for the first one, yes for the second one, and yes for the third one although your subtraction equation had the wrong year (its not 1847 its 1846) but the answer was right, 65.
It looks like the first 3 are because they all are blank x2.5 but the last one would be 8x2.5=20..
