I'm sorry I'm not entirely sure. But I think -2 and 4. If it's not multiple choice I say -2.
Yes. 2/3 is greater than 2/5. You can check this by cross multiplication or easier just look at the denominator and numerator. In this case the numerator is the same so it's easier in a sense that you need to look at the denominator. Since the denominator 3 is close to the numerator 2 it shows that it's almost a whole unlike the other fraction. You can also convert each fraction to decimals and compare it which is also easy. Just divide the numerator by the denominator and you've got a decimal. Hope this helps!

Answer:
325.6909
Step-by-step explanation:
Boys to girls ratio was 3:4 which means out of every 3+4= 7 students, 3/7 are boys and 4/7 are girls. But 40% of the girls left so only 60% are the 4/7. 60% is 0.6 in decimal form so to find how many women are really in the ratio (4/7)/0.6=0.95
the new ratio is 3/7:0.95 or 1:2.22 simplified so the number of boys b is b=w/2.22
