Q1.

Harpreet's family planned a picnic over the weekend. Her mother and father packed different food items to take along. The following is the list of fruits they carried — Watermelon – 3 kg, Pineapple – 1 kg 750 g, Apples – 1 kg 250 g, Mangoes – 2 kg. Among the fruits they carried, which one has the (a) highest weight? (b) least weight? (c) Arrange the items in descending order of their weight.

Answer

(a) The watermelon, 3 kg. (b) The apples, 1 kg 250 g. (c) Watermelon, Mangoes, Pineapple, Apples.

Before comparing, put every weight into the same unit. Grams is the easiest.

Change each one to grams. Watermelon 3 kg = 3,000 g. Pineapple 1 kg 750 g = 1,750 g. Apples 1 kg 250 g = 1,250 g. Mangoes 2 kg = 2,000 g.
Now they are all in grams, so just compare the numbers.
Order them from biggest to smallest — that is what descending means.

Fruit	Weight	In grams
Watermelon	3 kg	3,000 g
Mangoes	2 kg	2,000 g
Pineapple	1 kg 750 g	1,750 g
Apples	1 kg 250 g	1,250 g

3,000 g > 2,000 g > 1,750 g > 1,250 g

(a) Highest weight → Watermelon (3 kg)
(b) Least weight → Apples (1 kg 250 g)
(c) Descending order → Watermelon (3 kg), Mangoes (2 kg), Pineapple (1 kg 750 g), Apples (1 kg 250 g)

Why change to grams first: The pineapple and the apples both start with “1 kg”, so you cannot tell them apart by the kilogram alone. Once both are grams — 1,750 and 1,250 — the answer jumps out.

Total for fun: 3,000 + 2,000 + 1,750 + 1,250 = 8,000 g = 8 kg of fruit. That is a heavy picnic bag!

Q2.

Compare the weights using <, =, > signs. (a) 1 kg 600 g ____ 1,700 g (b) 1 kg 600 g ____ 1 kg 60 g (c) 10 kg 35 g ____ 10035 g (d) 1 kg 600 g ____ 2 kg 500 g (e) 5 kg 50 g ____ 4 kg 500 g (f) 900 g + 7,000 g ____ 7 kg + 900 g

Answer

(a) < (b) > (c) = (d) < (e) > (f) =

Use the same three steps every time.

Change both sides into grams. Then both sides speak the same language.
Compare the two numbers.
Write the sign — the open mouth always faces the bigger number.

Part	Left side in g	Right side in g	Sign
(a) 1 kg 600 g … 1,700 g	1,600 g	1,700 g	<
(b) 1 kg 600 g … 1 kg 60 g	1,600 g	1,060 g	>
(c) 10 kg 35 g … 10035 g	10,035 g	10,035 g	=
(d) 1 kg 600 g … 2 kg 500 g	1,600 g	2,500 g	<
(e) 5 kg 50 g … 4 kg 500 g	5,050 g	4,500 g	>
(f) 900 g + 7,000 g … 7 kg + 900 g	7,900 g	7,900 g	=

(a) 1,600 < 1,700 → 1 kg 600 g < 1,700 g
(b) 1,600 > 1,060 → 1 kg 600 g > 1 kg 60 g
(c) 10,035 = 10,035 → 10 kg 35 g = 10035 g
(d) 1,600 < 2,500 → 1 kg 600 g < 2 kg 500 g
(e) 5,050 > 4,500 → 5 kg 50 g > 4 kg 500 g
(f) 900 + 7,000 = 7,900 and 7,000 + 900 = 7,900 → equal

Look carefully at (e). The right side has the bigger gram number (500 against 50), and that tricks many students. But the kilograms are counted first, and 5 kg beats 4 kg. Kilograms are worth a thousand times more than grams, so they decide first — just as rupees decide before paise.

Remember the sign: Think of a crocodile's mouth. It always opens towards the bigger meal. 1,600 < 1,700 — the mouth opens to 1,700.
