Test: Decimals- 2 - Class 5 MCQ

A fraction and a decimal for the part of the school that consists of boys are

Given expression:

2000 + 200 + 20 + 2 + ²⁄₁₀ + ²⁄₁₀₀ + ²⁄₁₀₀₀ + ²⁄₁₀₀₀₀

Step 1: Add the whole numbers first:

2000 + 200 + 20 + 2 = 2222

Step 2: Convert the fractional parts into decimal form:

• ²⁄₁₀ = 0.2
• ²⁄₁₀₀ = 0.02
• ²⁄₁₀₀₀ = 0.002
• ²⁄₁₀₀₀₀ = 0.0002

Step 3: Sum the decimal parts:

0.2 + 0.02 + 0.002 + 0.0002 = 0.2222

Step 4: Add this to the sum of whole numbers:

2222 + 0.2222 = 2222.2222

Therefore, the value of the expression is 2222.2222, which corresponds to option B.

Required number

To solve the equation, we need to find what number divides 727.111 to give 7.27111.

We can observe that 7.27111 is 100 times smaller than 727.111. So, we divide 727.111 by 100.

727.111 ÷ 100 = 7.27111

Thus, the correct answer is Option B: 100

Amount of flour left = 5.00 - 2.25 = 2.75.
Amount of sugar left = 3.50 - .75 = 2.75.

The total rainfall over the first five days was calculated by adding the daily rainfall:

• Day 1: 1.27 cm
• Day 2: 3.25 cm
• Day 3: 2.79 cm
• Day 4: 2.57 cm
• Day 5: 1.37 cm

Adding these values gives a total (1.27 + 3.25 + 2.79 + 2.57 + 1.37) cm = 11.25 cm of rain.

Solution:

• Each curtain requires 2.5 m of cloth.
• Mrs. Radha Puri ordered 25 curtains.
• Total cloth needed = 2.5 m x 25 = 62.5 m.

1m = 1000 km
∴
