A) Determine whether the ratios are equivalent.
1. 4 to 8 and 1:2 → Equivalent
2. 6 to 10 and 3:5 → Equivalent
3. 6:21 and 2:6 → Not equivalent
4. 7:14 and 21:42 → Equivalent
5. 2 to 7 and 1:3 → Not equivalent
B) Find the unknown value in each equivalent ratio.
1. 2:3 = x:9 → x = 6
6:7 = 18:21 → x = 21
3:4 = 27:x → x = 36
2. 4:6 = 12:18 → x = 18
2:5 = x:15 → x = 6
4:7 = 20:x → x = 35
3. 7:4 = 21:x → x = 12
20:15 = 4:x → x = 3
x:2 = 7:7 → x = 2
