Is this correct? In pea plants, the allele for green pods is G. The allele for yellow pods is g. In the offspring 27 (75 percent) had green pods and 9 (25 percent) had yellow pods. What are the parents genotypes? How do you know? The parents genotypes are GG and gg. Because the dominant allele masked the recessive allele. In the offspring, 3/4 were green and 1/4 were yellow. The green pea pod masked the yellow pea pod.

Looks good to me

It does NOT look good to me. From your answer all the children would be Gg genotype. Both parents need to be heterozygous for that trait to get the percentages of offspring described. Do a Punnett square.
