Introduction to addition or subtraction of fractions with different denominator 3/5+1/3

1 answer:

6 0

You must find the same denominator by finding the closest common factor of both.
In this case it would be 15 because both 5 and 3 go into 15.
You then have to multiply the numerator by the number you multiplied to get the denominator.
So you multiply
Nevermind just look at the pic.

Step-by-step explanation:

Given line is passing through the points (3, 60) & (6, 50)

Therefore, slope of line:

$m = \frac{50 - 60}{6 - 3} = - \frac{10}{3} \\ y - intercept \: (b) = 70 \\ equation \: of \: line \: in \: slope \: intercept \\ form \: is \: given \: as : \\ y = mx + b \\ \huge \red{ \boxed{\therefore \: y = - \frac{10}{3} x + 70}} \\ which \: is \: the \: required \: equation.$
