4/? = ? / 9 this is an equivalent fraction problem. i need to find the missing numbers to make it an equivalent.

Set ? as x, and cross-multiply.

so x^2= 36

x = 6 or x = -6

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

homozygous. one is homozygous, while two is heterozygous.
