Are the ratios 6:4 and 19:12 equivalent?

1 answer:

4 0

Answer: No, they are not.

Step-by-step explanation: To see if ratios are equivalent, you have to simplify them. 6:4 can be simplified to 3:2 but 19:12 cannot be simplified anymore. Since 3:2 is not equal to 19:12, they are not equivalent.

What is the value of v? 1 / 4 (v – 7) = 2

belka [17]

1/4 (v - 7) = 2

1/4v - 1/4 (7/1) = 2

1/4v - 7/4 = 2

1/4v = 15/4

Multiply by 4/1 on both sides to get v

(4/1) 1/4v = 15/4 (4/1)

v = 60/4

v = 15

Given a bag of 5 blue, 3 green, and 8 red marbles.. What is the probability of picking a blue

Anvisha [2.4K]

$b = 5, \: g = 3, \: r = 8$

$total = 5 + 3 + 8 = 16$

$p(b) = \frac{5}{16}$

$p(g |without \: replacement|) = \frac{3}{16 - 1} = \frac{3}{15} = \frac{1}{5} \\$

$p(b \: and \: g) = \frac{5}{16} \times \frac{1}{5} = \frac{1}{16}$

To get the answer we can use proportion
220 ----------------95.3%
x -------------------100%
Crossmultiply now
220*100%=95.3%*x
22000=95.3x /:95.3
