Question

Solve for b


5/b = 45/36

Answer 1

Hey there!

5/b = 45/36
First you have to CROSS MULTIPLY
Like: 5 • 36 = 45 • b

5 • 36 = 180
45 • b = 45b

New equation; 180 = 45b

Turn your equation around

45b = 180

DIVIDE both of your sides by 45

45b / 45 = 180 / 45
Cancel out: 45 / 45 because that gives you 1
Keep; 180 / 45 because that helps us solve for our equation (or the value of your “b”)

New equation: 180 / 45 = b
Solve above and you have the result of b

180 / 45 = 4

Therefore the answer of b is : 4

b = 4 ☑️

Good luck on your assignment and enjoy your day!

Answer 2

Answer:

B=4

Explanation:

5/b = 45 / 36

You can solve this question with 2 ways:

first:

Rule: if a/b = c/d, we can say a.d = b.c

That's why 5.36 = 45.b

180 = 45b

b=4

Second way;

5/b = 10/2b = 15/3b..you know

therefore 45/5 =9

36/9 = 4

Hope this helps ^-^
