PLEASE HELP! WILL MARK BRAINLIEST!! Adele, Barbara and Collette share $680 in the ratio 9: 7:4.

(a) Show that Adele receives $306.
(b) Calculate the amount that Barbara and Collette each receives.

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

happy to

pls mark as brainliest
