1. Solve Exercise 1 on page 54 Math 5

Solution Method:
Subtracting two decimal numbers:
- Write the first number above, the second number below so that the digits in the same row are aligned, and the decimal points of each number are also aligned
- Place the subtraction sign in the middle to the left of the numbers
- Place a horizontal line below the second number, one space away

- Subtract as with natural numbers, from right to left
- Place the decimal point in the result directly below the decimal point of the subtracted and subtracting numbers.

3. Solve Exercise 3 on page 54 Math 5

Problem:
A container holds 28.75 kg of sugar. 10.5 kg of sugar is taken out, then another 8 kg is taken out. How much kilogram of sugar is left in the container?

Solution Method:
- Given quantities:
+ 1 container: 28.75 kg of sugar
+ First withdrawal: 10.5 kg of sugar
+ Second withdrawal: 8 kg of sugar
- Quantity to find: The remaining kg of sugar in the container.
- Solution steps:
+ Step 1: Find the total kg of sugar withdrawn in two steps by adding the kg of sugar taken out in the first and second withdrawals.
+ Step 2: Find the kg of sugar remaining in the container by subtracting the total kg of sugar withdrawn in two steps from the initial kg of sugar in the container.

Answer:
The total amount of sugar taken out is:
10.5 + 8 = 18.5 (kg)
The remaining amount of sugar in the container is:
28.75 − 18.5 = 10.25 (kg)
Answer: 10.25 kg of sugar.

Frequently Asked Questions

What are the steps for subtracting two decimal numbers in Math 5?

To subtract two decimal numbers, write the first number above and the second below, aligning the decimal points. Place the subtraction sign between them, draw a line below the second number, and subtract as with whole numbers, ensuring the decimal point in the result aligns with those in the original numbers.

How do I solve Exercise 3 on page 54 of Math 5?

To solve Exercise 3, first determine the total sugar withdrawn by adding the amounts from both withdrawals (10.5 kg + 8 kg = 18.5 kg). Then subtract this total from the initial amount of sugar in the container (28.75 kg - 18.5 kg) to find the remaining sugar, which is 10.25 kg.

Is there a guide available for solving exercises in Math 5?

Yes, a comprehensive guide to solving exercises in Math 5 is available. It covers various problems, including detailed methods for subtracting decimal numbers and provides complete solutions for exercises on specific pages.

Can I review previous exercises from Math 5 before solving new ones?

Yes, students can review solutions to earlier exercises from pages 51 and 52 of Math 5 to reinforce their understanding before tackling new exercises on page 54.
