Question

This is from the chapter of Ratio
someone pls send attachment or explain answer by typing to me ​

Answer 1

Step-by-step explanation:

15/18 = 5×3/6×3

So, 5/6 = 5×2/6×2 = 10/12

Then, 10/12 = 10×2.5/12×2.5= 25/30..

$\huge\bold\red{Solution}$

Yes mate this question is from ratio chapter in a way we can solve it as we do find the missing number in a proportion or by cross multiplication.

• 15/18=15:18
• ?/6=x:6

So now,

• 15:18::x:6

• =>18x=15×6
• =>18x=90
• =>x=90÷18
• =>x=5

Hence,The missing numerator of the fractions x/6 is 5.

$\huge\bold\red{Verifying}$

• 15/18=5/6
• =>15÷3/18÷3=5/6
• =>5/6=5/6
• =>0=0

:.our answer is correct!

Now for the next fraction i.e.,10/?

Now the same thing we will do here as well.

Instead of 15/18 there will be 5/6.

• =>5/6=5:6
• =>10/x=10:x
• =>5:6::10:x

• =>5x=6×10
• =>5x=60
• =>x=60/5
• =>x=12

hence,The value of x is 12.

$\huge\bold\red{Verifying}$

• =>5:6:10:12
• =>60:60
• =>0:0

hence proved!

Now for the last one as well we will do the same.

• 10/12=10:12
• ?/30=x:30
• =>10:12:x:30

• =>12x=10×30
• =>12x=300
• =>x=300÷12
• =>x=25

:.Value of x is 25

$\huge\bold\red{Verifying}$

• =>10:12::25:30
• =>300:300
• =>0:0

hence verified!

:.The fractions were:-

• 15/18=5/6=10/12=25/30
