Answer 2

Answer: 45/19

Explanation:

Based on the given conditions, formulate: ÷45 + x ÷ 2.5 = 1

Convert decimals to integers: x / 45 + 10 x / 25 = 1

Reduce the fraction: x /45 + 2x / 5 = 1

Multiply both sides of the equation by the common denominator:

x time 45 / 45 +

2x × 45 / 5= 45

Reduce the fractions: x + 18x = 45

Combine like terms: 19x = 45

Divide both sides of the equation by the coefficient of variable: x =45 / 19

so the answer Is 45 /19
