2 equivalent fractions for 9/15

Mathematics
1 answer:
Hitman42 [59]3 years ago
4 0
The easiest to find equivalent fractions is to multiply both the numerator and denominator by the same integer.  

For Example, an equivalent fraction for 9/15 is 18/30.  I got this answer by multiplying 9*2=18 and 15*2=30.

Another equivalent fraction for 9/15 is 27/45 because 9*3=27 and 15*3=45.

******Note
Just make sure that you always multiply the numerator and denominator by the same number, or else your fractions won't be equivalent!!

Sonja [21]

Answer: The interest rate is .166%

Step-by-step explanation:

So what I did was divide $50(Amount at the end) by 6 (the number of months). Which would give me the amount of money he made per month ($8.333...). So then $8.333.../$5000(Total $) is .166...% (Interest rate)

Find the area of the triangle
BARSIC [14]

Answer:

The Area of Δ ABC = 219.13

Step-by-step explanation:

<em>The hard part about this problem is finding the area without the height</em>

The formula to do this is Area = \sqrt{S(S-A)(S-B)(S-C)}

A, B, C represent the sides

S represents \frac{1}{2} (A + B + C)

In this equation, we will make the base be A, and the other two sides will be B and C

<u>Sides B and C are the same length</u> because they meet at a 90° angle

Lets plug the numbers into the variables

A = 28

B= 21

C= 21

<u>Remember:</u> S represents  \frac{1}{2}  (A + B + C)

S =  \frac{1}{2} (28 + 21 + 21)

S =  \frac{1}{2} (70)

S = 35

<em>Lets plug the numbers into the Area Formula now!</em>

Area = \sqrt{35(35 - 28)(35 - 21)(35 - 21)}

According to the order of operations, we need to do the calculations in parentheses <u>first</u>

35 - 28 = 7

35 - 21 = 14

35 - 21 = 14

14 x 14 x 7 = 1372

1372 x 35 = 48020

\sqrt{48020} = 219.13

The Area of Δ ABC = 219.13
