To find the number that must be added to -19 to get -11, you can set up the equation: -19 + x = -11. Solving for x, you add 19 to both sides, resulting in x = -11 + 19, which simplifies to x = 8. Therefore, the number that must be added to -19 is 8.

To determine the smallest number that must be added to 403 to make it divisible by 8, first find the remainder when 403 is divided by 8. The remainder is 3 (since 403 ÷ 8 = 50 with a remainder of 3). To make it divisible by 8, you need to add 5 (8 - 3 = 5). Therefore, the smallest number to add is 5.
If: 6x+8 = 32 Then: x = 4

The fourth number is 8.
Positive 29.... -21 + 29 = 8
To find the number that must be added to -19 to get -11, you can set up the equation: -19 + x = -11. Solving for x, you add 19 to both sides, resulting in x = -11 + 19, which simplifies to x = 8. Therefore, the number that must be added to -19 is 8.

403÷8 gives 50 as quotient and 3 as remainder. Dividend- remainder=divisor ×quotient 403-3=8*50 which is 400. our value is 403 So increase divisor 8*51=408. 403+5 gives 408. So 5 must be added to 403 to get a no divisible by 8.
If: 6x+8 = 32 Then: x = 4
No number can satisfy these conditions: To have a remainder of 1 when divided by 6, the number must be odd (as all multiples of 6 are even and an even number plus 1 is odd) To have a remainder of 2 when divided by 8, the number must be even (as all multiples of 8 are even and an even number plus 2 is even) No number is both odd and even. → No number exists that has a remainder of 1 when divided by 6, and 2 when divided by 8.
Assuming that the given number is 5/6, the other must be 7 1/6.
