Morgan knows that 15 pounds

of hamburger meat will make

60 hamburgers. If Morgan needs to

make 100 hamburgers for the

picnic, how much hamburger meat

does she need to buy?

25 pounds of hamburger meat will make 100 hamburgers

Step-by-step explanation:

if 15 pounds of hamburger meat will make 60 hamburgers then

 1 pound of hamburger meat will make,

      15 pounds of hamburger meat 60 hamburgers

       1 pound of hamburger meat ? (X)

by cross multiplying, 60 * 1 = 15 * (X)

                                   60 = 15(X)

      (X) = 60 / 15 = 4,

therefore,  1 pound of hamburger meat 4 hamburgers.

so, ? (X) pound of hamburger meat 100 hamburger

also by cross multiplying from above,

                   100 * 1 = 4 * (X)

                     100 = 4 (X)

therefore (X) = 100 / 4 = 25

so, 25 pounds of hamburger meat will make 100 hamburgers

idk lol

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
