Question

3 .... :3=10 (2 ост) 77: .... = .... (5ост)4 .... :7= .... (5ост)9:2= .... (1ост)​

Answer 1

$32 \div 3 = 10$ (остаток 2)

$77 \div 6 = 12$ (остаток 5)

$47 \div 7 = 6$ (остаток 5)

$9 \div 2 = 4$ (остаток 1)

Answer 2

To solve the given equations, let's break them down one by one:

1. 3 .... :3 = 10 (2 ост)

The equation states that when an unknown number is divided by 3, the quotient obtained (ignoring the remainder) is 10, and the remainder is 2.

To solve for the unknown number, we can multiply 10 by 3 and add 2 to get the result:

10 * 3 + 2 = 32

Therefore, the missing number is 32.

2. 77 : .... = .... (5 ост)

The equation states that when 77 is divided by an unknown number, the quotient obtained has a remainder of 5.

To solve for the unknown number, we can start by subtracting 5 from 77 to get the dividend:

77 - 5 = 72

Now we need to find a number that divides 72 and leaves a remainder of 5. Let's check the possible options:

72 ÷ 2 = 36 (no remainder) 72 ÷ 3 = 24 (no remainder) 72 ÷ 4 = 18 (no remainder) 72 ÷ 5 = 14 (remainder of 2) 72 ÷ 6 = 12 (remainder of 0) 72 ÷ 7 = 10 (remainder of 2) 72 ÷ 8 = 9 (no remainder) 72 ÷ 9 = 8 (remainder of 0)

Based on the options, we can see that when 72 is divided by 7, the remainder is 2.

Therefore, the missing number is 7.

3. 4 .... :7 = .... (5 ост)

The equation states that when an unknown number is divided by 7, the quotient obtained (ignoring the remainder) is 4, and the remainder is 5.

To solve for the unknown number, we can start by multiplying 4 by 7 and then adding 5 to get the result:

4 * 7 + 5 = 33

Therefore, the missing number is 33.

4. 9 : 2 = .... (1 ост)

The equation states that when 9 is divided by 2, the quotient obtained is unknown, but the remainder is 1.

To solve for the unknown quotient, we divide 9 by 2:

9 ÷ 2 = 4 remainder 1

Therefore, the missing quotient is 4.

I have filled in the missing numbers in each equation based on the given remainders and calculated results.
