Question

There are $900$ seashells on the beach. Woody collects them in packets of $10,$ Coco collects them in packets of $100,$ and Nutsy collects them in individual packets. Complete the following sentence:
Woody will make _(i)_ packets, Coco will make _(ii)_ packets, and Nutsy will make _(iii)_ packets.

• A. $\left(i\right)90,\left(ii\right)900,\left(iii\right)900$
• B. $\left(i\right)90,\left(ii\right)90,\left(iii\right)9$
• C. $\left(i\right)90,\left(ii\right)9,\left(iii\right)900$
• D. $\left(i\right)9,\left(ii\right)90,\left(iii\right)900$

Answer 1

The correct option is C $\left(i\right)90,\left(ii\right)9,\left(iii\right)900$

Say:
There are $900$ seashells on the beach.
Woody collects them in packets of $10.$
Coco collects them in packets of $100.$
Nutsy collects them in packets of $1.$
Let’s calculate the number of packets made by Woody, Coco, and Nutsy.
Steps:
$900$ can be represented as $9$ hundreds using place value.
So, Coco will collect the seashells in $9$ packets with each packet containing $100$ seashells.
We know that, $1$ hundred $=10$ tens
$9$ hundreds $=90$ tens
So, Woody will collect the seashells in $90$ packets with each packet containing $10$ seashells.
Nutsy will collect the seashells in $900$ packets.
So, option C is the answer.
