Answer» ONG>Answer: ? = 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 uncompleted 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 |
