Answer:
39/50
Explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.78=0.781
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
0.781×100100=78100
Find the Greatest Common Factor (GCF) of 78 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
78÷2100÷2=3950
Therefore
X=3950
In conclusion,
0.78=3950
