Question

Mrs Wong planted 3 tulips for every 4 daffodils. Which of the following could be the total number of tulips and daffodils that Mrs. Wong planted.

Answer 1

this denotes proportionality, so the numbers must be proportional

in other words be multiplied by the same amount

we can chek

A.

no because

`\begin{gathered} 3*10=30 \\ 4*11=44 \end{gathered}`

3 and 4 should be multiplied by the same number

B.

`\begin{gathered} 3*11=33 \\ 4*11\\e34 \end{gathered}`

multiplying by the same number does not match the result

C.

`\begin{gathered} 3*(34)/(3)=34 \\ 4*(33)/(4)=33 \end{gathered}`

3 and 4 should be multiplied by the same number

D.

`\begin{gathered} 3*12=36 \\ 4*12=48 \end{gathered}`

3 and 4 are multiplied by the same number and the result matches

the correct option is D
