An ovum will have an X chromosome regardless, but a sperm has a 50% chance of having either an X or a Y chromosome, so there's a 50% chance a zygote will be XY (male) and 50% that it will be XX (female).
Half the world's population are born girls because when the egg gets fertilized, the chance of it becoming a girl is 50%.
mytosis creates sex cells - either eggs (in girls) or sperm (in boys). They have 1/2 the number of chromosomes. When an egg and sperm combine, they create one full cell - one half plus one half = one whole. The fetus is created from that one full cell.

The statement can be true if the family has a total of five children, with two boys and three girls. The phrase "half of which are boys" can also be interpreted as meaning that two out of the five children are boys, which is indeed half of four, but not of five.

Still working on the test. At first glance you know that at least one third of the class is still working on it (half the girls are one third of the class). And since over half the boys have finished, you know the total remaining is less than half. You can figure it out using any numbers to set it up, but let's use 20 girls and 10 boys as the simplest. So 10 girls and 8 boys have finished for a total of 18, which leaves 12 still working on it. 12/30 is 6/15ths which is 2/5ths which is the same as 40%.
More than half of the girls at my school, including me, LOVE boys like that. (They're better than the obnoxious, pervy, jerks that don't care the least bit about you.)
