What is an expression?
Expression in maths is defined as the collection of the 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.
Solve an equation of proportions:
4/5 ton 5/6 bridge
Then (4/5) x (1 bridge) = (5/6 bridge)x.
Solve this for x by multiplying both sides of the equation by 6/5:
(6/5)(4/5) = x
24/25 tons of concrete are needed to complete the entire bridge.
Therefore, the amount of concrete required to cover the entire bridge is 24 / 25.
