Answer: There are 56 boys in the 10th grade
Step-by-step explanation:
Step 1
ratio of boys to girls in the 10th grade is 8 :13
Number of girls= 91
To find the number of boys, we first find the total number of boys and girls in the 10th grade
Step 2
Now the total ratio= 8 +13=21
Number of girls = ratio of girls/ total ratio x Total number of students
91=13/ 21 x Total number of students
Total number of students =21 x 91 / 13 =147
Step 3
Therefore Number of boys =ratio of boys/ total ratio x Total number of student
8/21 x 147=56
Answer:
x = 10
Step-by-step explanation:
In the last step, you can see that the fraction has been multiplied by its reciprocal , making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply · :
6 · 5 = 30
3 · 1 = 3
<u><em>So now you should have the fraction:</em></u>
x =
<u><em>But, you can still simplify the fraction by dividing 30 by 3:</em></u>
x = 10
