Question

The mast of a ship is of the length 6 km 885 m. The pirates use fabric pieces, each of length 85 m for making the mast.
How many pieces will they require for making the mast?

• A. 81
• B. 83
• C. 85
• D. 79

Answer 1

The correct option is A 81

The pirates have to make the mask of the ship of length $6km885m$.
Each fabric piece measure $=85m$.

∴ To get number of fabric pieces, divide $6km885m$ by $85m$.

First converting $6km885m$ to $m$,
$\Rightarrow 6km885m=6\times 1000m+885m$
$\Rightarrow 6km885m=6885m$.

So, here,
Divisor = $85$
Dividend = $6885$

Let's write $6885$ in expanded form.
$6885$ = $6000$ + $800$ + $80$ + $5$

Now, solving the division process using box method,



You got partial quotients as:
$70$ , $10$ , $0$ and $1$

∴ Final quotient will be:
$70$ + $10$ + $0$ + $1$ $=81$

So, the pirates will require $81$ pieces to make the mast of the ship.
