Answer:

The sum must be greater than 1

Step-by-step explanation:

Two fractions that are greater than 1/2 let's say

<u>Example 1</u>

3/4 and 7/8, the sum will be

3/4+7/8 with LCM of denominator as 8 sum=\frac {(3*2)+7}{8}=\frac {13}{8}=1\frac {5}{8} which is more than 1

<u>Example 2</u>

6/9 and 5/8 with the LCM of denominator as 72, the sum=\frac {(6*8)+(5*9)}{72}=\frac {93}{72}=1\frac {7}{24} which is greater than 1

<u>Example 3</u>

8/9 and 7/9 with the LCM of denominator as 9, the sum=\frac {8+7}{9}=\frac {15}{9}=1\frac {2}{3} which is greater than 1

Which of the matrixes can be added together? Choose all that apply.
katen-ka-za [31]
<h3>Answer: A and C</h3>

Both matrices are 1 x 4 matrices. This notation says there is 1 row and 4 columns. The number of rows must match up, as well as the number of columns, in order for matrix addition to be possible. This is so the corresponding elements pair up and add together. For instance, the 5 and -2 pair up and add together for matrices A and C.

Select the expression that has a value of 96.45
leonid [27]

Given:

Number is 96.45.

To find:

The expression that has a value of 96.45.

Solution:

In option a,

0.9645\times 10^2=0.9645\times 100

0.9645\times 10^2=96.45

In option b,

9.645\div 10^1=\dfrac{9.645}{10}

9.645\div 10^1=0.9645\neq 96.45

In option c,

964.5\times 10^3=964.5\times 1000

964.5\times 10^3=964500\neq 96.45

In option d,

9645\div 10^3=\dfrac{9645}{1000}

9645\div 10^3=9.645\neq 96.45

Therefore, the correct option is a.

What percentage of 22 is 8.8​
scoray [572]

Answer:   40%

Step-by-step explanation:

Let the percentage of 22 that gives 8.8      = x%  ---------------------------1

Therefore,

                                                   x% of 22      = x/100 x 22 ------------------2

since this gives 8.8, we now equate  to equation 2

                                                        x/100 x 22 = 8.8

                                                   (22 x  X )/100 =  8.8

                                                           22x/100 =   8,8

   Now cross multiply to solve for x

                                                                 22x  = 8.8 x 100

                                                                 22x  = 880

  Now divide through by 22 to get the require value of x

                                                                     x  = 880/22

                                                                     x = 40%
