<h3>Answer: the fraction -8/117</h3>

----------------

First, convert to an improper fraction

3 & 1/4 = 3 + (1/4)

3 & 1/4 = (12/4) + (1/4)

3 & 1/4 = 13/4

The mixed number 3&1/4 turns into the improper fraction 13/4

---------------

-2/9 divided by (3&1/4) = -2/9 divided by 13/4

To divide two fractions, you flip the second one and then you multiply

"-2/9 divided by 13/4" turns into "-2/9 times 4/13" after this happens

Then you multiply straight across. The numerators stick together. The denominators stick together.

numerators: -2*4 = -8

denominators: 9*13 = 117

We end up with the fraction -8/117

This cannot be reduced as there are no common factors (other than 1) between 8 and 117.

would you choose to use a hundred chart to solve 90- 80? why or why. not ? if not. which strategy would work better?
notsponge [240]
I would use a tens chart because both numbers are multiples of 10, and there both under 100, so it would work out better if u use a tens chart, since the numbers are in the tens place and would give u a product of 10.

i hope this helps u <span />

Murrr4er [49]

Answer:

x= 50

Step-by-step explanation:

the total measure of all the angles of a triangle is always 180 so you subtract 65 two times (once for each of the other angles) and that will ive you the remaining degrees which in the case would be x.

1. 180 = triangle

2, 180- 65- 65= 50

a — b = 3

then a= 3+b

a + b = 5

3+b +b = 5

b=1

a= 3+b

a=3+1=4
