Answer 2

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

1. __:7=8 (remainder 5)

Let's assign the unknown value as x. The equation can be written as x divided by 7 equals 8 with a remainder of 5.

Mathematically, this equation can be represented as:

x = 8 * 7 + 5

x = 56 + 5

x = 61

So, the first missing number is 61.

2. ___:12=7 (remainder 9)

Similarly, let's assign the unknown value as y. The equation can be written as y divided by 12 equals 7 with a remainder of 9.

Mathematically, this equation can be represented as:

y = 7 * 12 + 9

y = 84 + 9

y = 93

Therefore, the second missing number is 93.

3. 68:___=9 (remainder 9)

Now, let's assign the unknown value as z. The equation can be written as 68 divided by z equals 9 with a remainder of 9.

Mathematically, this equation can be represented as:

68 = 9 * z + 9

68 - 9 = 9z

59 = 9z

Dividing both sides by 9:

z = 59 / 9

z = 6.55 (approximately)

Therefore, the third missing number is approximately 6.55.

To summarize: First missing number: 61 Second missing number: 93 Third missing number: Approximately 6.55
