Question

Plz help i don’t understand it

Answer 1

since you cross multiply, 2 times 4 is 8 and 6 times the p is 6p so divide both sides by 6 and 8/6 is 1.33 so 1.33=p

Answer 2

Answer:

p = 4/3

Step-by-step explanation:

The problem is showing you a proportion and how to solve it.

Let's use the following proportion to explain the cross multiplication method.

$\dfrac{a}{b} = \dfrac{c}{d}$

Start with the proportion above. To get rid of parentheses, multiply both sides by b and by d.

$bd\dfrac{a}{b} = bd\dfrac{c}{d}$

Simplify:

$ad = bc$

Now look again at the proportion we started with.

$\dfrac{a}{b} = \dfrac{c}{d}$

The two products we ended up with are the same you have circled in your problem. Those products are the result of cross multiplying.

Now let's do your problem and go straight to the cross multiplication.

$\dfrac{6}{2} = \dfrac{4}{p}$

6 and p are circled together, so the left side becomes 6p.

2 and 4 are circled together, so the right side becomes 2 * 4.

After cross multiplying, we have

6p = 2 * 4

6p = 8

Divide both sides by 6 to find p.

p = 8/6

Reduce the fraction

p = 4/3

What the problem shows you is that to simplify a proportion, set the cross products equal to each other, and solve the equation.
