A large rectangular piece of card is (√5 + √√45)cm long and √√27 cm wide. A small rectangle √√3 cm long and √5 cm wide is cut out of the piece of card.
(√5 +√45)-
√5
√√3
Show that the area of the card that is left as a fraction of the area of the large rectangle is

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

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9
