Reduce the fraction to its lowest terms by extracting and cancelling out 7.
5/392 can be written as <em><u>5</u></em><em><u> </u></em><em><u>:</u></em><em><u> </u></em><em><u>3</u></em><em><u>9</u></em><em><u>2</u></em><em><u> </u></em><em><u> </u></em>or further simplified to <em><u>0</u></em><em><u>.</u></em><em><u>0</u></em><em><u>1</u></em><em><u>2</u></em><em><u>7</u></em><em><u>.</u></em>

If you want the answer in 3 ratios itself, then you can do the work easily by just dividing the numbers by the common number (here it is 7).
So, 35 : 56 : 49 will become ⇨ <em><u>5</u></em><em><u> </u></em><em><u>:</u></em><em><u> </u></em><em><u>8</u></em><em><u> </u></em><em><u>:</u></em><em><u> </u></em><em><u>7</u></em><em><u>.</u></em>
