How do i solve divide 5/8 by 50%

Answers

50% is $(50)/(100)$
We have two ways to do this, pick your favor:
either by fractions:
$(5)/(8)$ ÷ $(1)/(2)$
( $(50)/(100) = (1)/(2)$
Multiply by the reciprocal of $(1)/(2)$ which is 2(flip it)

$(5)/(8)$ × 2 = $(5)/(4)$ = 1.25

Or change them to decimals:
$(5)/(8) = 0.625$
$(50)/(100)$ = 0.5

0.625 ÷ 0.5

0.5 I 0.625
multiply by 10 to make it easier to divide(it still gives us the same answer)
0.5 × 10 = 5
0.625 × 10 = 6.25
1.25
5 I 6.25
-5
12
-10
25
-25
0

0.625 ÷ 0.5 = 1.25

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the difference between two times a number and four is eight. The expression will be written as below:-

2x - 4 = 8.

2x = 8 + 4

x = 12 / 2

x = 6

Therefore, the algebraic equation will be written in this way 2x - 4 = 8.
