Question

Write the decimal expansion of the rational number 35÷50 without actual division

Answer 1

Step-by-step explanation:

35÷50 = (35*2)÷(50*2) = 70÷100 = 0.7

Additional info

[50 = 5*5*2.. if we can make pairs of (5,2) we can write the decimal form of a number without actual division. so we multiplied numerator and denominator by '2' so that we get 2 pairs of (2,5) in denominator. 50*2=5*5*2*2.]
