The weight in kilograms of an object that weighs 70 pounds is 31.5 kilograms.
<h3>How to calculate the value?</h3>
Given that the number of kilograms that an object weighs varies directly with the number of pounds and that an object weighs 45 kilograms weighs 100 pounds.
This will be:
y = mx
y = weight in kilograms
x = weight in pounds
k = constant
45 = 100k
Divide
k = 45/100
k = 0.45
The equation will be written as y = 0.45x
Therefore, when the object weighs 70 pounds, this will be:
y = kx
y = 0.45 × 70
y = 31.5
The weight in kilograms is 31.5kg

Hi there!
Below is the fraction we are working with:
To simplify this fraction down to its lowest form, we see what number(s) can go into the numerator and the denominator evenly. We can start off with the number 2. 2 goes evenly into each number, can't it? :)
So, we can cut down to 
.
is already in it's simplest form. Now, we can see if they're equivalent. If not, we have to start all over.
Since equals 83.3, we have to make sure does, too.
Just divide the numerator by the denominator to see what you have.
5 ÷ 6 = 83.3 with a repeating decimal, so they're equivalent!
Hope this helps!
If you need anything else, don't just sit there - Let me know! :D
