The GCF stands for greatest common factor. To represent a sum by its GCF we need to use the distributive property and we need to first find the GCF of the numbers. Let's break each number by its factors:

We now multiply the numbers that appear on both.

We now apply the distributive property:
Answer:
use the pythagoras theorem ok for 3rd side
i.e. (5.6)²+(3.9)²=c²
Answer:
37.5%
Step-by-step explanation:
you have 8 slices that should represent 100% so 100 divide 8 is 12.5
12.5 multiply by the three red sections you have then you get 37.5%
Step-by-step explanation:
We can break this up into pieces, first we do, 7/8 - 1/4, find the least common denominator which is 8, so the equation will be 7/8 - 2/8, which we can now subtract and will give us, 5/8, now that we have done that, we can do 5/8 - 1/2. Since we know that half of 8 (our denominator) is 4. Then the equation would be 5/8 - 4/8, which brings us to 1/8 as our final answer.
Cheers!
