Question

write the value of x if 3:4=15:(15+x)​

Answer 1

Answer:

x=5

Step-by-step explanation:

Let us take these as Fractions

3:4 will be  $\frac{3}{4}$ and 15: 15+x will be  $\frac{15}{15+x}$

so  $\frac{3}{4}$ = $\frac{15}{15+x}$

Cross multiplying we get

3(15+x) = 4(15)

45+3x = 60

3x = 60-45

3x= 15

x=15/3= 5

Hope this helps
