Answer:

189 students

Step-by-step explanation:

  1. 2/9 = 6th grade
  2. 2/9 = 42 students
  3. So therefore, 2/9 = 42/x
  4. Let's break down the equation above. The original fraction is 2/9. The numerator represents the 6th grade students, and the denominator represents the total number of students in the school. So, if we expand that to actual numbers in the school, it would be 42 over the total number of students in the school (represented by x).
  5. Let's solve it now in the steps below
  6. Write out the equation: \frac{2}{9} = \frac{42}{x}  
  7. Cross multiply, then divide: 9 × 42 = 378, 378 ÷ 2 = 189
  8. So, the total students in the school are 189 students.

I hope this helps!

Dianna and Becky were playing on the same soccer team and took turns being goalie. They stoped 9 out of 10 shots made against th
vitfil [10]

Answer:

27 balls

Step-by-step explanation:

If Dianna and Becky stopped 9 out of 10 shots made against them.

It means they allowed in 1 out of 10 shots made against them.

This is best solved using ratios

Proportion of Shots Stopped : Proportion of Shots allowed=9:1

If the other team scores 3 points, it means the number of shots allowed =3

Let x be the number of shots stopped

Number of Shots Stopped : Number of Shots allowed=x:3

Therefore:

9:1=x:3

\frac{9}{1}=\frac{x}{3}

Cross multiplying

x=9 X 3 =27

Dianna and Becky stopped 27 balls from going into the net,
