Answer :
common denominator first. multiply 2/5 by 2 in the top and bottom so they all have a denominator of 10
7/10+4/10-1/10=10/10
10/10=1
7/10+4/10-1/10=10/10
10/10=1
Assuming mental math still follows the order of operations, you have
[tex] \frac{7}{10} + \frac{4}{10} - \frac{1}{10} = \frac{10}{10} = 1[/tex]
So the answer is 1.
[tex] \frac{7}{10} + \frac{4}{10} - \frac{1}{10} = \frac{10}{10} = 1[/tex]
So the answer is 1.
