Answer:
y = 1.1
Step-by-step explanation:
Proportion is a statement that two ratios are equal.
It can be written in two ways:
- Two equal fractions
= 
- Two equal sides a: b = c: d.
We can use cross products to find a missing term in it.
Let us solve the question
∵ The proportion statement is 
= 
→ Use the cross multiplication to find y
∵ y × 15.4 = 7.7 × 2.2
∴ 15.4y = 16.94
→ Divide both sides by 15.4 to find y
∵ 
= 
∴ y = 1.1

Answer:
The percentage rate per annum is 2.8%
Step-by-step explanation:
We need to multiply the principal by the time, then divide the interest by the product of P×T, so:

224 ÷ 8,000 = 0.028
Then we convert our final product to a percentage.
0.028 to a percent is 2.8%
