Answer:b) If there are 20 squares there will be 25 triangles.
c) There are 20 girls
Step-by-step explanation:
b) The ratio here is 4(squares):5(triangles), so if there are 20 squares you have to divide that by the original number of squares, 4. Once you get that, you multiply it by the number of triangles, 5. The work should look something like this:
20/4 = 5
5 x 5 = 25
c) For this one you have to add the total number of students within the ratio. Since there 5 girls and 2 boys, that is 7 people in total. Since you’re trying to reach a total of 28, you divide 28 by 7, which will give you 4. Now, you multiply 4 by the number of just girls, (5), which gives you a total of 20.
