Complete Question

Mickey went down to the pet store and bought 11 2/3 pounds of bird seed. Mickey gave 5/7 of the bird seed to Daisy, and Daisy gave 4/5 of her bird seed to Frank. Frank wanted to know how many pounds of bird seed he received. Drag and drop the expressions below to create the original expression and solve the problem step by step.

Answer:

The number of pounds of bird seed that Frank received is 6 2/3 or 20/3 pounds of bird seed.

Step-by-step explanation:

Step 1

Mickey went down to the pet store and bought 11 2/3 pounds of bird seed.

Initial number of bird seeds = 11 2/3 pounds

= 35/3 pounds of bird seeds

Step 2

Mickey gave 5/7 of the bird seed to Daisy.

The number of bird seed that Daisy received is calculated as:

5/7 of 11 2/3 pounds of bird seed

= 5/7 × 35/3

= 25/3 pounds of bird seed

= 8 1/3 pounds of bird seed

Hence,Daisy received, 8 1/3 pounds of bird seed.

Step 3

Daisy gave 4/5 of her bird seed to Frank. Frank wanted to know how many pounds of bird seed he received.

The number of pounds of bird seed that Frank received is calculated as:

4/5 of Daisy's bird seed

= 4/5 of 8 1/3 pounds of bird seed

= 4/5 × 25/3 pounds of bird seed

= 20/3 pounds of bird seed

= 6 2/3 pounds of bird seed

Therefore, the number of pounds of bird seed that Frank received is 6 2/3 pounds of bird seed

b) Drag and drop the expressions below to create the original expression and solve the problem step by step.

The expressions to get the final answer =

I) (11 2/3 × 5/7) . 4/5

II) (35/3 × 5/7 ) . 4/5

III) 25/3 . 4/5

IV) 20/3
