Explain why it is possible (and helpful) to compare ratios with decimals.
Ratios can be compared using decimals because they can be written as fractions; fractions can be converted to decimals, which are easy to compare.
Write 4 pints: 3 gallons as a fraction in simplest form
4/24 = 1/6

Not equivalent. 2/15 = 0.1333, 12/87 = 0.137
In 1749, this mammal was called "the lowest form of existence," however, they are now considered the world's undisputed pull-up champions, and have enough specialized arm muscles to sleep while hanging from tree branches. It takes 30 days for the animal to digest a single leaf, AND they are rendered blind in bright light. Who am I?
Sloth!
Write three ratios. The first must have a value that is GREATER than 1. The second must have a value that is LESS than 1. The third must have a value in between the values of the first and second. Answers must be written in x:y format.
Many correct answers. One example is 8:7, 1:4, 4:5
Express 18:5 as a decimal

This planet has a mean temperature of 462 C (that's 863.6 F) due to the high concentration of carbon dioxide in its atmosphere. It also has extremely high atmospheric pressure (equivalent to being 1 km below the surface of the ocean), AND one day on this planet is about equivalent to one year on Earth. Who am I?
