Step-by-step explanation:
1) take your known ratio (56/14) and divide to find the factor between the numbers so 56 /14 = 4. <u>4 is your ratio factor </u>
then working backwards:
42/ 4 = <u>10.5</u>
28/4 = <u>7</u>
3.5 * 4 = <u>14</u> It can also be seen as what number divided by 4 will give you 3.5
2) 2,416/ 60.4 is the known ratio now so divide to find the factor between the numbers. So 2,416/ 60.4 = 40. <u>40 is your ratio factor</u>
120.8 * 40 = <u>4832</u>
1208/40 = <u>30.2</u>
15.1 * 40 = <u>604</u>
You need to have variables one one side and constants on the other. ax - ax + by = c - ax by = c - ax by/b = (c - ax)/b y = (c - ax)/b
