Sagot :
[tex]1\frac{3}{5}[/tex]
Explanation:
-0.2 + (-¾) + 2.15 - (-⅖)
let's convert the decimal to fractions:
-0.2 = -2/10 = -1/5
2.15 = 215/100 = 43/20
-0.2 + (-¾) + 2.15 - (-⅖) = -1/5 + (-¾) + 43/20 - (-⅖)
Expanading the bracket:
Multiplication of same sign gives positive number. Multiplication of opposite signs give negative number.
= -1/5 -3/4 + 43/20 + 2/5
[tex]\begin{gathered} \text{The LCM = 20} \\ =\frac{-1(4)-3(5)+43+2(4)}{20} \\ \end{gathered}[/tex][tex]\begin{gathered} =\frac{-4-15+43+8}{20}=\frac{32}{20} \\ =\frac{8}{5} \\ =1\frac{3}{5} \end{gathered}[/tex]
