Answer:
There are 35 boys in the class.
Step-by-step explanation:
This question can be solved as a rule of three.
In science class, the girl to boy ratio is 3 to 7.
This means that for each 10 students, 7 of them are boys and 3 are girls.
So if for 10 students, 7 of them are boys, how many are boys for 50?
7 boys - 10 students
x boys - 50 students
There are 35 boys in the class.

Brazil population: 1.907×
Mexico population 1.123×
To find how much more the population was in Brazil than in mexico, you would subtract the Brazil population to Mexico's population:
The 's would not cancel out because they are representing further decimal places that aren't written, so you would subtract 1.907 and 1.123.
1.907 - 1.123= 0.784
Brazil's population is 0.784× larger than Mexico.
