Answer:
In a class of 28 students the ratio of girls and boys is 4:3. The number of girls in the class is 16.
Solution:
Let us consider total number of students in the class is “T”.
Let the ratio of the students (Girl and boys) in the class is G: B.
Given that total number of students in class (T) = 28
From question, given that ratio of girls and boys is 4:3. We can write this ratio as,
Number of girls (G) = 4x and number of boys (B) = 3x
We have to find the number of girls in class. The total number of girls present in the class is given as ,
The total girl students present in the class G =
=
Hence the total number of girls in the class is 16.
4x7=28
16 are girls and the balance is 12 boys

Any number that can be evenly divided by 24 without leaving a remainder is a multiple of 24.
We have,
Numbers that have 24 as a multiple includes:
24 (24 x 1)
48 (24 x 2)
72 (24 x 3)
96 (24 x 4)
120 (24 x 5)
144 (24 x 6)
168 (24 x 7)
192 (24 x 8)
216 (24 x 9)
240 (24 x 10)
and so on.
Thus,
Any number that can be evenly divided by 24 without leaving a remainder is a multiple of 24.

B. 5 + (-6) = -1
C. -5 + 6 = 1
D. -5 + (-6) = -11
What addition statement does this show?
Answers
Answer:
B) 5 + (-6) = -1
Step-by-step explanation:
First, take a look at the blue arrow on the bottom. It travels forwards 5 spaces, giving us +5. Because this arrow starts at 0, 5 will be the start of our equation. Next, take a look at the red arrow on the top. This arrow travels backwards 6 spaces, giving us -6. Here is what our equation should look like now:
5 + (-6) =
Now, solve for the answer. Follow the blue line forwards 5 spaces, then follow the red arrow backwards 6 spaces. The red arrow stops at -1, making our answer 5 + (-6) = -1.
Answer:
D. -5 + (-6) = -11
