if 3/4 = ?/12 ? then =
Answers
Answer:
? equals 9
Step-by-step explanation:
3/4= 9/12
we are changing the denominator to 12, so we are doing 4 times 3, giving 12 as the denominator. now we have to convert the numerator, and make sure its still in ratio. so we should multiply 3 with 3 too.
so basically, if you get a sum like this, first divide 12, the denominator with the uncomplete fraction, with 4, the complete fraction. with this we get 3. now multiply the numerator(3/4) the bold 3 with 3, giving 9
in the end it gives 9/12
(hope it helps, tho the explanation is kind of lame,but i dont know how to expain any better)
To find:
We have to find the value of ?
Step-by-step explanation:
Solution 1.
Given, 3/4 = ?/12
⇒ ?/12 = 3/4
⇒ ? = 3/4 * 12
⇒ ? = 3 * 3
⇒ ? = 9
∴ the value of ? is 9.
Solution 2.
Here 3/4 = (3 × 3)/(4 × 3) = 9/12
⇒ ? = 9
Final answer: ? = 9
NOTE:
For any ratio, we can find its equivalent ratios. Simply multiply both the numerator and the denominator by the same number (Natural Number).
If a : b be a given ratio, then we can find equivalent ratios,
a : b = 2a : 2b = 3a : 3b = 4a : 4b = 5a : 5b = ... ...
