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>
Answer:
The two such fractions are: 113/100 and -22/25.
Step-by-step explanation:
Let us assume two such fractions are P and Q.
⇒ P x Q = -1
and P + Q = 1/4
Now, to solve for the values of P and Q:
P + Q = 1/4 ⇔ Q = 1/4 - P
Substitute this value of Q in P x Q = -1, we get:
P x Q = -1
Now, solving this with the help of QUADRATIC Formula:
We get: P = 1.13 or P = -0.8825
Now, if P = 1.13, Q = -1/1.13 = -0.88 = -88/100 = -22/25
If P = -0.88, then Q = 1/0.88 = 1.13 = 113/100
Hence, The two such fractions are: 113/100 and -22/25.
