Step 1
- 2/12 = 5/28
- 2*28 = 12*5
- 56 = 60
False equation
Step 2
- No, because the cross products are not equal.
- The proportion is not true, because 2/12 and 5/28 are not equivalent ratios.
Solution (1):
We know that:
- Given proportion: 2:12 = 5:28
Step-by step calculations:
Simplify the LHS:
- 2:12 = 5:28
- => 1:6 = 5:28
Remember: (a:b = c:d) = (a x d = b x c)
Use cross multiplication:
- => 1:6 = 5:28
- => 28 = 30 (False)
Solution (2):
- No, because the cross products are not equivalent.
- The proportion is not true, because 2/12 and 5/28 are not equivalent ratios.
