Pip and Sara win some money and share it in the ratio 5:2. Pip gets £40. How much did Sara get?

Sara gets £16

Step-by-step explanation:

We know the ratio is 5:2 and we know Pip gets £40 so divide 40/5= 8

every 8 is equal to one portion of the fraction so 8x2= 16

To check 40:16 divide by 8 40/8=5 16/8=2    The ratio being 5:2

sorry not sure

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
