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
<em>No need to round it to the nearest tenth because the answer has no hundredth to round it to the tenth</em>
FYI - 14,15,16 are correct.
17. a) 7 (nearest integer), b) 6.8 (nearest tenth)
18. a) 14 (nearest integer), b) 13.8 (nearest tenth)
19. --> simplified to = 2
