Lcm of 12x and 40y! plz as soon as possible!

The least common multiple of 12x and 40y is 120xy.

Step-by-step explanation:

First, we need to get the prime factors of each number.

12x: 2 × 2 × 3 × X

40y: 2 × 2 × 2 × 5 × Y

Then, we need to see how many times each factor occurs in each factorization.

2 × 2 × 3 × X: 2 twice, 3 once, X once

2 × 2 × 2 × 5 × Y: 2 three times, 5 once, Y once

Finally, we need to multiply each factor the most number of times it occurs in either factorization.

The most times 2 appeared was 3 times.

3 once.

5 once.

X once.

Y once.

With that information, we do this:

2 × 2 × 2 × 3 × 5 × X × Y = 120xy

The least common multiple of 12x and 40y is 120xy.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
