Questions & Step-by-Step Solutions
In a class of 60 students, the ratio of boys to girls is 3:2. If the number of boys is increased by 5, what will be the new ratio of boys to girls? (2023)
Step 1: Understand the total number of students in the class, which is 60.
Step 2: Know the ratio of boys to girls is 3:2.
Step 3: Calculate the total parts in the ratio: 3 (boys) + 2 (girls) = 5 parts.
Step 4: Find out how many boys there are: (3 parts / 5 parts) * 60 students = 36 boys.
Step 5: Find out how many girls there are: (2 parts / 5 parts) * 60 students = 24 girls.
Step 6: Increase the number of boys by 5: 36 boys + 5 = 41 boys.
Step 7: The number of girls remains the same: 24 girls.
Step 8: Write the new ratio of boys to girls: 41 boys to 24 girls.
Step 9: Simplify the ratio if possible. The ratio 41:24 does not simplify further.
