Question

find the value of x if 2x/5 and 28/35 are equivalent rational numbers​

Answer 1

$\frac{2x}{5} = \frac{28}{35} \\ 2x \times 35 = {28}\times 5 \: \\ 70x = 140 \\ x = 2$

Answer 2

Answer:

x=2

Step-by-step explanation:

2x/5 = 28/35

2x = 28 * 5 / 35

2x = 28/7

x = 28/ 2 * 7

x= 2

2*2/5 = 28/35 (7  is commmon)  

( 4*7 is 28  5*7 is 35)

4/5 = 4/5
