The rules for converting fractions with denominators 10, 100, 1000, etc. into decimal fraction:
(i) Count the number of zeroes coming after 1 in the denominator.
(ii) Count an equal number of places in the numerator starting from the unit digit then place the decimal point to the left of the digit reached.
Let us consider some of the following examples;
1. Convert 819/100 to decimal.
Given, 819/100 This explanation will help you
Y =

x + 3
y = x - 4
Since both equations are equal to y, you can set the two values equal to each other and solve for x.

x + 3 = x - 4 Multiply both sides by 2
x + 6 = 2x - 8 Add x to both sides
6 = 3x - 8 Add 8 to both sides
14 = 3x DIvide both sides by 3
4
= x
Now, plug the x value into one of the original equations, I'll plug it into y = x - 4.
y = x - 4 Plug in the x value
y = 4

- 4 Subtract
y =
x = 4
and
y =
