What is 2/3÷12/19

Desiree is making guacamole for a party. The recipe she is using calls for 1/4 cup lime juice for every 4 avocados. If she plans to use 1 cup of lime juice, how many avocados does she need?

Rubio decides he is going to walk to his friend's house, which is 1 mile from his house. He can walk at a pace of 2/3 mile in 16 minutes. At this rate, how long will it take him to get to his friend’s house?
They better be right

To solve for 2/3 ÷ 12/19, we can multiply the first fraction by the reciprocal of the second fraction:

(2/3) * (19/12) = (2*19) / (3*12) = 38/36

We can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:

38/36 = 19/18

So, 2/3 ÷ 12/19 is equal to 19/18.

To find out how many avocados Desiree needs, we can set up a proportion based on the given recipe:

1/4 cups lime juice / 4 avocados = 1 cup lime juice / x avocados

Cross-multiplying, we have:

1 * x = 4 * 1/4

Simplifying, we get:

x = 1

So, Desiree needs 1 avocado.

To determine how long it will take Rubio to get to his friend's house, we can set up a proportion using the given information:

2/3 mile / 16 minutes = 1 mile / x minutes

Cross-multiplying, we have:

2/3 * x = 1 * 16

Simplifying, we get:

2x/3 = 16

Multiplying both sides by 3/2 to isolate x, we get:

x = (16 * 3)/2

Simplifying, we get:

x = 48/2

x = 24

Therefore, it will take Rubio 24 minutes to walk to his friend's house.

To solve the expression 2/3 ÷ 12/19:

Step 1: Change the division into multiplication by taking the reciprocal of the divisor.
2/3 ÷ 12/19 is the same as 2/3 * 19/12.

Step 2: Simplify the multiplication.
Multiply the numerators (2 * 19) to get 38, and multiply the denominators (3 * 12) to get 36.

Therefore, 2/3 ÷ 12/19 simplifies to 38/36.

Step 3: Simplify the fraction.
Divide the numerator and denominator by the greatest common divisor, which is 2.
38 / 2 = 19, and 36 / 2 = 18.

So, 2/3 ÷ 12/19 simplifies to 19/18.
