A small school has 42 boys. If the ratio of boys to girls is 7 : 1, how many, students are?
2 answers:
There are a total of 48 students. Being 42 boys as mentioned earlier and 6 girls total attending too.
Answer:
48
Step-by-step explanation:
Total ratio = 7 + 1 = 8
Let the total number of students be x
Number of boys.
7/8 × x = 42
7/8 x = 42
Multiply both sides by 8
8 × 7/8 x = 42× 8
7x = 336
Divide both sides by 7
7x / 7 = 336/7
x = 336/7 = 48
Therefore total number of students is 48

I believe the answer is a 20% increase because 12-10 equals 2. there is a 2 record difference so 2 out of 10 is 1/5 of the whole, but you have to convert the numbers and 1/5 of the whole of 100 is 20. sorry if that didn’t make much sense
