50/X = 40/100

50 × 100 = 40 × X

5000 = 40X

5000/40 = 40X/40

125 = X

X= 125

the equation is 
is/of       %/100

50 = is 
40 = % 
X = of
100 = 100
  
50 X 100 = 5,000
40 X x = 40x 

40x / 40 = x
5,000 / 40 = 125 

SO... x = 125

Tanzania [10]

Answer:

Step-by-step explanation:

Given that,

The number = 60

To find,

Factors of 60 greater than 1 = ?

Procedure:

As we know,

Any of various numbers multiplied together to form a whole.

To find the factors of a number, we will have to do its prime factorization.

So,

The prime factorization of 60:

1 * 2 * 2 * 3 * 5 = 60

Since the factors greater than 1 are asked, the factors would be;

2 * 2 * 3 * 5

Thus, 2 * 2 * 3 * 5 is the correct answer.
