5(4 • 3 + 3 • 4)=
480
300
120

Step-by-step explanation:

Our given equation is 5 (4 × 3 + 3 × 4)

Using The Order of Operations (AKA): PEMDAS, we need to solve this.

The "P" stands for parentheses. We do have them, so we need to solve the operations inside of them.

We don't have any parentheses inside.

The "E" stands for exponents. We don't have any, so we need to move on.

The "M" stands for multiplication. We have two multiplication symbols, so we need to solve them.

1.  5 (4 × 3 + 3 × 4)    

2.  5 (12 + 3 × 4)

3.  5 (12 + 12)

The "D" stands for division. We don't have any of them, so we need to move on.

The "A" stands for addition. We have one of them, so we need to solve.

4.  5 (12 + 12)

5.  5 × 24

Now that we only have the operation 5 × 24, we can go ahead and solve.

6.  5 × 24 = 120

So now we know that when using The Order of Operations to solve the equation: 5 (4 × 3 + 3 × 4) results in a 120.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
