Question

Help me with this 10 one

Answer 1

We know that 13/30 of flowers are roses, and 2/5 are orchids. These two flowers make

`(13)/(30)+(2)/(5)=(13)/(30)+(12)/(30)=(25)/(30)`

of the total number of flowers, implying that gladioli represent the remaining
`1-(25)/(30)=(30)/(30)-(25)/(30)=(5)/(30)=(1)/(6)`

So, if gladioli represent 1/6 of the total, and they are 7, then the total will be 6*7=42 flowers.
