Question

A 1/4-3/5+75/100

 

Answer 1

A=1/4 - 3/5 + 75/100

A=25/100-60/100+75/100

A=\(\frac{25-60+75}{100}\)

A=40/100

A=2/5

Answer 2

\(A=\frac{1}{4}-\frac{1}{3}+\frac{75}{100}\)

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

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

\(A=0-\frac{1}{3}\)

\(A=\frac{-1}{3}\)
