If you would like to solve (- 0.5) / (- 0.5) and - 50 / (- 0.5), you can do this using the following few steps:
(- 0.5) / (- 0.5) = 0.5 / 0.5 = 1
- 50 / (- 0.5<span>) = 50 / 0.5 = 50 / (5/10) = 50 / (1/2) = 50 * 2/1 = 100
</span>
The correct results would be: (- 0.5) / (- 0.5) = 1 and - 50 / (- 0.5<span>) = 100.</span>
Ok, It's hard to explain so I'll use an example.
1/5 + 2/15
now you try to find a number that goes into both for this example it would be 3
3*5=15 and then that equals the 2/15
so you then multiply 3 by the numerator getting the fraction
3/15 + 2/15
with the answer of
5/15 which can be reduced to
1/3
Answer:
Step-by-step explanation:
let x represent the denominator then x - 3 represents the numerator.
Increase the numerator by 1, that is x - 3 + 1 = x - 2
Increase the denominator by 3, that is x + 3, then fraction
= ( cross- multiply )
2(x - 2) = x + 3, that is
2x - 4 = x + 3 ( subtract x from both sides )
x - 4 = 3 ( add 4 to both sides )
x = 7
Thus original fraction is
=
