Hello There!

Dividing a fraction is the same thing as multiplying by its reciprocal.

This means that $\frac{3}{4}$ ÷ $\frac{5}{12}$ is the same as multiplying $\frac{3}{4}$ by $\frac{12}{5}$ .

So basically when you divide you leave the first fraction alone but the second fraction in this case, 5/12 you would flip the number on top and the number on bottom to 12/5.

HAVE A GREAT DAY!

A baseball is hit inside a baseball diamond with a length and width of 90 feet each. What is the probability that the ball will

professor190 [17]

90(squared) + 90 (squared) = C (squared)
(we use 90 because the base path is 90 ft long since the diamond is a square that makes all sides 90 ft long)
8100 + 8100 = c(squared)
16200 = c(squared)
we will get the square root of 16200 to get the diagonal length
C=127.3 ft, and since it is the diagonal distance we will device it to 2, to get the distance from the pitcher ro the 2nd base.
127.3/2 = 67.7 ft.
67.7 ft is the distance from the pitcher<span> to the 2nd base.</span>
