a = 20.4
b = 2.22
Step-by-step explanation:
This ratio can be written as 5.4/a = 1.8/6.8
Then we cross multiply;
5.4 * 6.8 = 1.8 * a
36.72 = 1.8a
36.72 / 1.8 = a
20.4 = a
We can also write the 2nd ratio as;
2.4/0.5k = 3.6 / 1 2/3
We cross multiply;
1 2/3 can written as 5/3
2.4 * 5/3 = 0.5k * 3.6
4.0 = 1.8k
4.0/1.8 = k
2.222** = k
