What is the ratio of total boys to total girls?
- A26:31
- B31:26
- C33:28
- D28:33
Solution & Step-by-step Explanation
Let's first compute the total number of boys and girls across all classes.
Total Boys=20+15+30+30+30+30=155
Total Girls=30+20+10+25+25+20=130
Now, calculate the ratio of boys to girls:
Ratio=
130
155
Dividing both numbers by their highest common factor (5):
Ratio=
130÷5
155÷5
=
26
31
Thus, the ratio of boys to girls is 31:26.
Total Boys=20+15+30+30+30+30=155
Total Girls=30+20+10+25+25+20=130
Now, calculate the ratio of boys to girls:
Ratio=
130
155
Dividing both numbers by their highest common factor (5):
Ratio=
130÷5
155÷5
=
26
31
Thus, the ratio of boys to girls is 31:26.
