What is 2/4 + 4/5 - 7/10 ? Please help

1 answer:

7 0

Make sure they have all common denominators
$\frac{2}{4} + \frac{4}{5} - \frac{7}{10}$

$\frac{2}{4} * \frac{5}{5} = \frac{10}{20}$

$\frac{4}{5} * \frac{4}{4} = \frac{16}{20}$

$\frac{7}{10} * \frac{2}{2} = \frac{14}{20}$

$\frac{10}{20} + \frac{16}{20} - \frac{14}{20}$

Add $\frac{10}{20} + \frac{16}{20} = \frac{26}{20}$
$\frac{26}{20} - \frac{14}{20} = \frac{12}{20}$

To simplify, you must find the largest common factor which 4
In $\frac{12}{20}$
12÷4=3 and 20÷4=5

The answer is $\frac{3}{5}$

3(x+6)=2(4x+14) what is the value of x?

GrogVix [38]

Hi there

3(x + 6) = 2(4x + 14)
3x + 18 = 8x + 28
3x - 8x = 28 - 18
-5x = 10
x= 10/-5
x = -2

Here it is :)
