100=25+75, rewrite 25+75 using their GCF and multiplication.
To rewrite the expression 25 + 75 using their greatest common factor (GCF) and multiplication, we need to find the GCF of 25 and 75 first.
The prime factors of 25 are 5 x 5 (5^2), and the prime factors of 75 are 5 x 5 x 3 (5^2 x 3).
The GCF is the product of the common prime factors raised to the lowest exponent, so the GCF of 25 and 75 is 5^2, which is 25.
Now, we can rewrite the expression 25 + 75 as the product of the GCF and the sum of the remaining factors:
25 + 75 = 25 x (1 + 3)
So, 25 + 75 can be rewritten as 25 x 4.
To rewrite 25+75 using their greatest common factor (GCF) and multiplication, we need to find the GCF of 25 and 75 first.
The GCF of 25 and 75 is 25.
Now, let's rewrite 25+75:
25 + 75 = 25 * 1 + 25 * 3
Since we found that the GCF of 25 and 75 is 25, we can rewrite both 25 and 75 as multiples of 25:
25 + 75 = 25 * 1 + 25 * 3
= 25(1 + 3)
Thus, we can rewrite 25+75 as 25(1 + 3).
25 x 4 + 75 x 4 = 100
What?
25 * 4 = 25 * 1 + 25 * 3
by the way 75 * 4 = 300
