Question

find a number such that when it is added to two third of itself the,result is 70 ​

Answer 1

Answer :

first you need to put this into an equation so:

first you need to put this into an equation so:x+2/3x=70

first you need to put this into an equation so:x+2/3x=70You want to have fractions with the SAME denominators so make the fractions have 6 as a denominator:

$\frac{x}{1} + \frac{2x}{3} = \frac{70}{1} \\ so \\ \frac{6x}{6} + \frac{4x}{6} = \frac{420}{6}$

So simplifying this down we get:

$\frac{10x}{6} = \frac{420}{6}$

Now,

we multiply to get rid of the denominators so :

60x = 2520x = 42

we can also check,

42/3 = 1414x2=2842+28=70

follow me...
