Is 2/3 equal to 2/4 because the numerator are equal
Masja [62]
No. For fractions to be equal, both the numerators and denominators have to be proportional.

Since both denominators are 2, the denominators would have to be just 3 or just 4.

Identity the composite number represented by the prime factorization below
Korolek [52]

Answer:look below

Step-by-step explanation: The prime factorization of number is the break down into factors which are prime numbers (numbers without factors except 1 and itself). The factors 22 and 32 are composite numbers since they have more than 1 and itself as factors. They are not prime.

However, the factorization of 22 * 32 * 5 will equal a number. 22*32*5 = 3, 520. But it does not match the solutions given.
