Answer: -\frac{5}{6}

When you multiply fractions, you multiply straight across and simplify.

-\frac{2}{3}*\frac{5}{4}           [multiply]

-\frac{10}{12}               [simplify]

-\frac{5}{6}

Now, we know that the product is -\frac{5}{6}.

Which of the following numbers can be expressed as repeating decimals? 3 over 7, 2 over 5, 3 over 4, 2 over 9
Maurinko [17]

Hello!

Let's think about the denominators we have. A seventh goes on forever in no specified order. A fifth an a fourth have set decimal values, 0.2 and 0.25, so they are not repeating decimals. A ninth is 0.111111..., it repeats like this forever in a specified order. Therefore, 2/9, or 0.222222...., would be a repeating decimal.

Therefore, our answer is \boxed {\frac{2}{9}}.

I hope this helps!

A scooter was bought at Rs 42,000. its value depreciated at the rate of 8% per annum. find its value after one year​
Alona [7]

Answer:

Rs 38,640

Step-by-step explanation:

<u>Pay attention:</u>

A = P(1+r/100)^n

The principle (p) : Rs 42,000

Rate of interest (r) : 8%

Time (n) : 1 years

Exact Amount (a) : P(1-R/100)^n

Value:

A = 42,000(1 - 8/100)^1

A = 42,000(1 - 2/25)

A = (42,000 * 23)/25

A = 1,680 * 23

A = Rs 38,640
