Question

Which expression could be used to find the missing value in x 3/5 = 4/7?

a) 3/5 * 4/7

b) 5/3 * 7/4

c) 5/3 * 4/7

d) 3/5 * 7/4

Answer 1

The correct expression to find the missing value is c) 5/3 * 4/7.

The answer is option ⇒c

Step-by-step explanation:

To find the missing value in the equation x 3/5 = 4/7, you can use cross multiplication.

Cross multiplying both sides gives you the expression (3/5) * x = (4/7).

By using cross multiplication, we set up an equation where the product of the numerator of one fraction and the denominator of the other fraction is equal to the product of the denominator of the first fraction and the numerator of the second fraction. This allows us to solve for the missing value.

To find x, you can then multiply (4/7) by the reciprocal of (3/5), which is (5/3).

So, the correct expression to find the missing value is c) 5/3 * 4/7.
