Alex buys 2 1/2 pounds of grapes. he buys 1 1/4 times as many pounds of apples as grapes. how many pounds of apples does he buy?

So if, 2 1/2 = 5/2 and 1 1/4 = 5/4,
then 5/2 * 5/4 = 5*5 / 2*4 = 25/8 is simplified to 3 1/8 pounds.

Grapes = 2 1/2 pounds = 5/2 pounds
Apples = 1 1/4 times grapes = 5/4 times grapes

Apples = 5/4 * 5/2 = 25/8 pounds = 3 1/8 pounds

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

Answer is negative 2
