<span>First, we determine the factors of 45. We can immediately note that 45 is the product of 9 and 5. Out of 9 and 5, 9 can further be expressed into the product of 3 and 3. The prime factorization therefore is,
45 = 3 x 3 x 5
Since the factors in the right-hand side of the equation are already prime numbers then, this factorization can no longer be written in simpler forms.</span>
Umm what? I don’t think i can answer this cause i can barely read it.
D. Color
My explanation for this answer is that Color is for atomic mass which in this case mass is not the answer so my answer is D. Color
Hope this Helps you !
2/5 = x/10
2/5 x 2 = 4/10
x= 4
2/5 = 4/10
