First you have to make your denominators the same. You have 5 and 7 as your denominators. 5 x 7 = 35 So we can use 35 as the common denominator. So you have

1/5 = 7/35

<u>1/7 = 5/35  </u>   now you can subtract

         2/35

Hope that I was able to help you. :-)

Convert the fractions so they both have the same denominator (bottom part of the fraction)

1/5 = 7/35

This is because 5*7=35, so 1*7=7

1/7 = 5/35

This is because 7*5=35, so 1*5 =5

Then subtract the top numbers to get the answer:

\frac{7}{35}-\frac{5}{35} = \frac{2}{35}

Answer:

score = 63

Step-by-step explanation:

1.  To write the proportion take the score of the test over the number of points and set it equal to the percent over 100

score         90

----------- = -----------

70               100

Using cross products

100 * score = 90*70

100 score = 6300

Divide by 100

100/100 * score = 6300/100

score = 63

Simplify. x/4x+x^2
djyliett [7]

\bf \cfrac{x}{4x+x^2}\implies \cfrac{\begin{matrix} x \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}}{\begin{matrix} x \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~(4+x)}\implies \cfrac{1}{4+x}\qquad \{x|x\in \mathbb{R}, x\ne -4\}

if you're wondering about the restriction of x ≠ -4, is due to that would make the fraction with a denominator of 0 and thus undefined.

m_a_m_a [10]

Answer:

-11/12

Step-by-step explanation:

Add 5/8+3/4 (6/8) which is 11/8 and then get -2/3 - 5/6 which simplifies to -3/2

Multiply -3/2 by 4 to get it to like terms

11/8 / -12/8

Multiply and then simplify.
