b)x/5= 4/10

Answer 1

A) 3/4 = x /4
3 =x

B) x/5 = 4/10
10x = 20
X = 20 /10
X = 2

Answer 2

a) 
$\frac{3}{4} =\frac{x}{4} \\ \\ 3(4) =x(4) \\ \\ 12=4x \\ \\ \frac{12}{4}=x \\ \\ 3=x$

3/4 = 3/4

b)
$\frac{x}{5} = \frac{4}{10} \\ \\ x(10)=4(5) \\ \\ 10x = 20 \\ \\ x= \frac{20}{10} \\ \\ x=2$

2/5 = 4/10
