Eight times the reciprocal of a number equals 4 times the reciprocal of 9 .

2/9

Step-by-step explanation:

Call the unknown number n

Therefore, we can express your question in the following manner

8 * n = 4 * 9

n = 36/8

But we know that n is a reciprocal of a number, so we need to flip the numerator and denomiator in n

8/36 = 2/9

n

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
