Answer:
23 1/13
Step-by-step explanation:
You have done a pretty good job of writing the problem, negative 300 divided by negative thirteen. It can be translated directly to your favorite calculator (see attachment) for a solution.
If you want to perform the division by hand, the particular method of writing the problem depends on the method of division you want to use. (Several styles are taught these days). Numerous web sites and videos explain <em>long division</em> in all its detail. The second attachment shows an example where a decimal fraction result is obtained. The decimal fraction is an infinite repeating decimal with a 6-digit repeat.
For starters, you would generally convert both numbers to positive numbers, since the result of 300/13 is the same as the result of -300/-13 and positive numbers are easier to deal with.

<em>Comment on symbols</em>
(The symbol ÷ generally means the same thing as the symbol /. Both mean "divided by". In some cases, the symbol ÷ is given the meaning "everything to the left of it divided by everything to the right of it." This is often the case when it is used as part of a compound fraction: 3/5÷4/3, for example. The preferred representation of such a division is (3/5)/(4/3), with parentheses clearly identifying numerators and denominators.)
When divided by 5, 3 subtracted from x divided by 2 equals to 6
Answer:
So you pretty much just solved your math by yourself :)
Step-by-step explanation:
Answer: 19
Step-by-step explanation:
80 - 23 = 57 signatures left
57 signatures divided by him and his 2 friends
57 / 3 = 19
They need 19 signatures each
Answer:
Nancy's age is 11years and Khaled's age is 10years
Step-by-step explanation:
Let Nancy's present age be x
Let Khaled's present age b y
3 years ago
Nancy = x - 3
Khaled = y - 3
If 3 years ago, Nancy’s age was more than Khaled’s age by 2, then;
x-3 = y-3 + 2
x - 3 = y - 1
x- y = -1+3
x - y = 2 ...1
4 years from now,
Nancy = x+4
Khaled = y+4
If by 4years from now, twice Nancy’s age will be more than Khaled’s age by 16, then;
2(x+4) = y+4 + 16
2x+8 = y+20
2x-y = 20-8
2x-y = 12 ....2
Subtract 1 from 2;
x - 2x = 1 - 12
-x = -11
x = 11
Since x - y = 1
11 - y = 1
y = 11-1
y = 10
Hence Nancy's age is 11years and Khaled's age is 10years
