How do you solve #x/2 = 4/7#?

Answer 1

Eva Abramson

The answer is #x=8/7#

There are several ways of solving such equation:

1) Multiplying both sides by #14# to eliminate fractions:

#7x=8#

#x=8/7#

Multiplying "in a cross" This is multiplying numerator of one side by denominator of the other and vice versa:

#x*7=4*2#

#x=8/7#

To solve the equation x/2 = 4/7, you can cross-multiply. Multiply the numerator of the first fraction (x) by the denominator of the second fraction (7), and multiply the numerator of the second fraction (4) by the denominator of the first fraction (2). This gives you 7x = 8. To isolate x, divide both sides of the equation by 7. The solution is x = 8/7.
