Step-by-step explanation:
2:6[sugar is to flour]
1:3[to simplify divide both sides by two]
Sugar : Flour
2 : 6 (substitute the numbers of cups)
1 : 3 (simplify by reducing. divide both sides by 2)
The ratio is 1:3.
48/31 is already at its simplest form, however you can change it to a mixed fraction which would become 1 17/31
3.45
