I got 14/15
You have to find the lowest common denominator which is 15.
Answer:
This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.
Now, the circunference of a circle can be written as:
C = 2*pi*r
where:
pi = 3.14
r = radius = half of the diameter = 3.5m/2 = 1.75m
Then replacing those values in the equation for the circumference we have:
C = 2*3.14*1.75m = 10.99 m.
And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)
We can safely round up the circumference to the next whole number, C = 11m
To do this, you make an equation; .18 = .75x
divide .75 on both sides, and x equals .24
Answer:
9/10
Step-by-step explanation:
If you are truly "struggling," you might want to consider working the problem using your calculator. It will give you a decimal answer: 0.9.
You know this is nine tenths, or 9/10 when written as a fraction.

When adding fractions, you are instructed to use a common denominator. Usually, that instruction is to find the "least" common denominator. In many cases, that simplifies reducing the fraction that will be the answer.
However, <em>any</em> common denominator will do. The easiest one to find is the product of the denominators. Here, that is 2·5 = 10.
The first fraction has a denominator of 2, so to make its denominator 10, you need to multiply it by 5/5.
The second fraction has a denominator of 5, so to make its denominator 10, you need to multiply it by 2/2.

Effectively, we have used the formula for the sum of two fractions:
(a/b) +(c/d) = (ad +bc)/(bd)
1/2 + 2/5 = (1·5 +2·2)/(2·5) = 9/10
