Answer:
2.5 or 10/4
Step-by-step explanation:
2÷4/5
Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,
2/1÷4/5
But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)
2/1×5/4
And tadaa! you get your answer
10/4
You can also simplify it!
5/2
2(2x+1)= (2 x 2x) + (2 x 1) = 4x + 2
