Answer 1

Answer:b, c, a

Explanation:

Given

`(3)/(8)` of the flowers are red

`(1)/(3)` of the flowers are white

to get the white flowers, add the two fraction and subtract them from 1

fraction of white flowers

Part- B

Fraction of flower red or Pink

`\Rightarrow (3)/(8)+(1)/(3)=(17)/(24)`

Part-C

fraction of flowers that are white

`\Rightarrow 1-(3)/(8)-(1)/(3)\\\\\Rightarrow 1-(9+8)/(24)\\\\\Rightarrow 1-(17)/(24)=(7)/(24)`
