Answer 1

28:3=9(ост 1)
30:4=7(ост 2)
15:4=3(ост 3)
36:5=7(ост 1)
31:3=10(ост 1)

Answer 2

28:3=9 (ост 1) 9*3+1=28
30:4:7 (ост 2) 4*7+2=30
15:4=3 (ост 3) 3*4+3=15
36:5=7 (ост 1) 5*7+1=36
31:3=10 (ост 1) 10*3+1= 31

Answer 3

Division with Remainder

Let's solve the division problems with remainders step by step.

Step 1: Perform Division Without Remainder

First, let's perform the divisions without remainders.

1. 28 ÷ 3 2. 30 ÷ 4 3. 15 ÷ 4 4. 36 ÷ 5 5. 31 ÷ 3

Performing these divisions without remainders gives us the following results: 1. 28 ÷ 3 = 9 with a remainder of 1 2. 30 ÷ 4 = 7 with a remainder of 2 3. 15 ÷ 4 = 3 with a remainder of 3 4. 36 ÷ 5 = 7 with a remainder of 1 5. 31 ÷ 3 = 10 with a remainder of 1

Step 2: Perform Division with Remainder

Now, let's verify these results by performing the divisions with remainders.

1. 28 ÷ 3 = 9 remainder 1 2. 30 ÷ 4 = 7 remainder 2 3. 15 ÷ 4 = 3 remainder 3 4. 36 ÷ 5 = 7 remainder 1 5. 31 ÷ 3 = 10 remainder 1

So, the results obtained from performing the divisions with remainders match the initial results.

This confirms that the divisions with remainders have been correctly calculated.
