Boxes of Sweet

Mr Shrinathan, a sweet shop owner, has several orders for 1 kg Kaju-katli but he has to pack them in different sized boxes.

Write down the number of boxes needed to pack 1 kg Kaju-katli in the blank space:

Question 1. Mr Das wants the sweets in boxes weighing 500 g each.

Solution:

Since 1 kg = 1000 g and 1000 g = 500 g + 500 g = 2 × 500 g,
Mr. Shrinathan needs 2 boxes of 500 g each to pack 1 kg of Kaju Katli.

Question 2. Mrs Fernandes wants the sweets in boxes weighing 250 g each.

Solution: 

Since 1 kg = 1000 g and 1000 g = 250 g + 250 g + 250 g + 250 g = 4 × 250 g,

Mr. Shrinathan needs 4 boxes of 250 g each to pack 1 kg of Kaju Katli.

Question 3. Mrs Khan wants the sweets in boxes weighing 100 g each.

Solution: 

Since 1 kg = 1000 g and
1000 g = 10 × 100 g (i.e., ten 100 g portions),

Mr. Shrinathan needs 10 boxes of 100 g each to pack 1 kg of Kaju Katli.

Question 4. Mr Patel wants the sweets in boxes weighing 50 g each.

Solution: 

Since 1 kg = 1000 g and
1000 g = 10 × 100 g = 10 × (2 × 50 g) = 20 × 50 g,

Mr. Shrinathan will need 20 boxes of 50 g each to pack 1 kg of Kaju Katli.

(a) How many 500 ml bottles will fill a 11 bottle?

Solution: 

Since 11 = 1000 ml = 500 ml + 500 ml
= 2 × 500 ml

Thus, two 500 ml bottles will fill a 1 l bottle.

(b) How many 250 ml bottles will fill 11 bottle?

Solution:
Since 1 l = 1000 ml
= 250 ml + 250 ml + 250 ml + 250 ml
= 4 × 250 ml

Thus, four 250 ml bottles will fill a 1 litre bottle,

(c) How many 100 ml bottles will fill a 1 l bottle?

Solution:
Since 11= 1000 ml
= 100 ml + 100 mlm + 100 ml + 100 ml + 100 ml + 100 ml + 100 ml + 100 ml + 100 ml + 100 ml
= 10 × 100 ml

Thus, ten 100 ml bottles will fill a 1 l bottle.

(d) How many 100 ml

250 ml in \(\frac{1}{2}\) l = ________
250 ml in 750 ml = ________
100 ml in \(\frac{1}{2}\) l = ________.
100 ml in 800 ml = ________

Solution:
\(\frac{1}{2}\)l = \(\frac{1}{2}\) × 1000 ml = 500 ml
= 250 ml + 250 ml
= 2 × 250 ml
So, there are two 250 ml in \(\frac{1}{2}\) l.

750 ml = 250 ml + 250 ml + 250 ml
= 3 × 250 ml

So, there are three 250 ml in 750 ml.

\(\frac{1}{2}\) l = \(\frac{1}{2}\) × 1000 ml = 500 ml
= 100 ml + 100 ml + 100 ml + 100 ml + 100 ml
= 5 × 100 ml

So, there are five 100 ml in \(\frac{1}{2}\) l.
800 ml = 100 ml + 100 ml + 100 ml + 100 ml + 100 ml + 100 ml + 100 ml + 100 ml
= 8 × 100 ml
So, there are eight 100 ml in 800 ml.
