2. Question 2

   3 marks

   A farmer had 7,250 kg of sugar cane. He sold 4,375 kg. How many kg were left?

   (3 marks)

   Marking scheme

   The sugar cane he sold is no longer his, so subtract it from what he had. (1)

   $7,250-4,375$: regroup, since $0$ ones cannot take $5$ and $5$ tens cannot take $7$ tens. (1)

   This gives $2,875$. Check: $2,875+4,375=7,250$. (1)

   Final answer: $2,875$ kg.

   Marking scheme

   Subtract column by column, starting from the ones. (1)

   $2$ ones cannot take away $5$, so regroup: $12-5=7$ ones; carrying on through the tens, hundreds and thousands gives $4,467$. (1)

   Final answer: $4,467$. Check: $4,467+1,875=6,342$.

11. Question 11

    2 marks

    Find the difference between 9,005 and 4,678.

    (2 marks)

    Marking scheme

    "Difference" means subtract the smaller number from the larger: $9,005-4,678$. (1)

    There are not enough ones or tens, so regroup from the thousands: $9,005$ becomes $8$ thousands, $9$ hundreds, $9$ tens and $15$ ones. Subtracting gives $4,327$. (1)

    Final answer: $4,327$. Check: $4,327+4,678=9,005$.

17. Question 17

    3 marks

    A school library had 8,500 books. 3,764 books were borrowed. How many books remained?

    (3 marks)

    Marking scheme

    Books borrowed have left the library, so take them away from the total. (1)

    $8,500-3,764$: there are no ones or tens to take from, so regroup from the hundreds first. (1)

    This gives $4,736$. Check: $4,736+3,764=8,500$. (1)

    Final answer: $4,736$ books.
