Answer:

\frac{7}{120}  of seed planted in each flower pot.

Step-by-step explanation:

Given:

Total number of marigold seeds packages Trixie have=  ¾

Answer:

62 is your answer

6 × (36 ÷ 12)² + 8, you can also write 36 ÷ 12 as a fraction, which would look like this: 36/12

Step 1: 6 × 36/12² + 8 = 6 × 3² + 8

Step 2: Multiply 6 and 9

(6)(9)+8 = 54+8

Step 3: Then you add 54 and 9 and you get 62
