Question

75%+1/4-1/4:0,25+1/8:0,125-1/2:0,5

Answer 1

Không khó đâu nhé em:

\(75\%+\frac{1}{4}-\frac{1}{4}:0,25+\frac{1}{8}:0,125-\frac{1}{2}:0,5\)  

\(=\frac{3}{4}+\frac{1}{4}-\frac{1}{4}:\frac{1}{4}+\frac{1}{8}:\frac{1}{8}-\frac{1}{2}:\frac{1}{2}\)

\(=\frac{3}{4}+\frac{1}{4}-1+1-1\)

\(=1-1+1-1\)

\(=0\)
