Please help! I’ll give brainliest!! 1. What is a proportion? Show example.
2. How do you solve propositions?
3. What is the “easy” method to solving proportions?

1.a part, share, or number considered in comparative relation to a whole.

1/3 = 2/6

2.If a proposition is true, then we say it has a truth value of "true"; if a proposition is false, its truth value is "false". For example, "Grass is green", and "2 + 5 = 5" are propositions. The first proposition has the truth value of "true" and the second "false".

3.

Don't confuse cross multiplication with cross cancellation. You use cross cancellation to make multiplying fractions easier. Set the two cross products equal to each other. 1 · 2 = 2 and 0.5 · f = 0.5f.

the answer is 31.27mph

you probably already have the answer but anyways it's b. 15.0
