Question

The ratio of the number of boys and girls in the class is 4:3. There are 45 students in a class. How many students are boys?

Answer 1

26

Explanation:

as the ratio is given you should divide ratio of boys by total ratio and multiply it by the total number of students, kinda like how in percentages you divide partial value/total value x 100, just in this case the total is 45 instead of 100. So
`(4)/(7) * 45` = 25.7 which have to be rounded to 26
