Comparing masses of different objects using kitchen scales in a math worksheet.

Let's solve the problem step by step based on the image provided.

We are given three objects placed on scales, each showing their mass in kilograms (kg). Let's analyze each scale:

---

Step 1: Read the mass from each scale

#### (a) Sack of rice
- The scale shows the pointer pointing at 5 kg.
- So, the mass of the sack of rice is 5 kg.

#### (b) Cake
- The scale shows the pointer pointing at 2 kg.
- So, the mass of the cake is 2 kg.

#### (c) Bag
- The scale shows the pointer pointing at 7 kg.
- So, the mass of the bag is 7 kg.

Now, let’s answer the questions using these values:

---

(a) The mass of the sack of rice is 5 kg.
✔

(b) The mass of the cake is 2 kg.
✔

(c) The mass of the bag is 7 kg.
✔

(d) The cake is the lightest.
Because 2 kg < 5 kg < 7 kg → cake is lightest.

(e) The bag is the heaviest.
Because 7 kg > 5 kg > 2 kg → bag is heaviest.

(f) The cake is 3 kg lighter than the sack of rice.
Calculation: 5 kg (rice) - 2 kg (cake) = 3 kg

(g) The bag is 5 kg heavier than the cake.
Calculation: 7 kg (bag) - 2 kg (cake) = 5 kg

(h) The bag is 2 kg heavier than the sack of rice.
Calculation: 7 kg (bag) - 5 kg (rice) = 2 kg

---

✔ Final Answers:

(a) 5
(b) 2
(c) 7
(d) cake
(e) bag
(f) 3
(g) 5
(h) 2

📝 Explanation Summary:

We read the masses directly from the analog scales:
- Rice: 5 kg
- Cake: 2 kg
- Bag: 7 kg

Then used subtraction to compare differences and determined which object was lightest/heaviest.
