Answer:

I am actaully learning this right now!

Step-by-step explanation: Hope this helps!

1) Multiply the numerators.

Multiply the Denominators

Simplify

2) When working with whole numbers you have to make it improper.

Multiply the denominator by the whole number and whatever you get you to add the numerator with it and that is how you make it improper.

Answer:

19 and 29/32 or 19.90625

Step-by-step explanation:

So the 1st Way: We could simplify it and make them into improper fraction in a way like this:

13/4 * 49/8

We can then just multiply the top row and the bottom row:

13 * 49 = 637

4 * 8 = 32

637/32 = 19 and 29/32

The 2nd Way: We could literally add 6 and 1/8, 3.25 times

(I'm so sorry this is a way lol but I couldn't think of another)

6.125 + 6.125 + 6.125 + 6.125(0.25) = 18.375 + 1.53125 = 19.90625 :P

Find the difference and write it in simplest form 7 3/8 - 2 7/9

Papessa [141]

Well first you have to turn the mixed number into a improper fraction.
7 2/8=59 over 8
2 7/9=25 over 9
Then u would multiply the 59 by 9 and 8 by 9 and u should get 531 over 72 and for the second fraction u should multiply the 25 by 8 and the 9 by 8 and you should get 200 over 72 as a improper fraction.
Then you have to subtract 531 over 72 by 200 over 72 and u should get 231 over 72 which is 4 and 43 over 72 when simplified.
The answer: 4 43/72
Hope this helps!!!!

Need help with 1st question !!! Will mark brainlest!!

You would calculate this answer with the Pythagorean theorem. The formula is a² + b² = c², which basically means that the sum of two sides squared would equal the side that is missing.
Currently, we are given 6.5 for side 1. The angle measurments we are given is 45º and 90º [the right angle], which means that if we subtract the sum of 45 and 90 from 180 [the total degree amount of every triangle] we can get the missing angle. With the missing angle, we can calculate the length of the second side.
45º + 90º = 135º. 180º - 135º = 45º.
Now that we have the angles of all three sides [45º, 90º, 45º] we can find the second length of the triangle. The fact that two angles are the same [45º] means that the length is also the same.
Thus proving that M is also 6.5 in length, we can square 6.5 and add both sides to each other once squared.
6.5² = 42.25.
42.25 + 42.25 = 84.5.
The square root of 84.5 is 9.19, or 9.2 rounded.
