[tex]\begin{aligned} \bold{1.} \: \frac{8}{9} \times \frac{2}{3} &= \bold{\frac{16}{27}} \\ \\ \bold{2.} \: 0.98 + 0.76 & = \bold{1.74} \\ &= \frac{^{ \green{87}} \cancel{174}}{ \cancel{100} _{\green{50}}} \\ &= \frac{87}{50} \\ &= \bold{1\frac{37}{50}} \\ \\ \bold{3.} \: 5 \frac{6}{10} - 2 \frac{1}{5} &= \frac{56}{10} - \frac{11}{5} \\ & = \frac{56}{10} - \frac{11 \times \blue{2}}{5 \times \blue{2}} \\ &= \frac{56}{10} - \frac{22}{10} \\ &= \frac{^{ \green{17}} \cancel{34}}{ \cancel{10}_{\green{5}}} \\ &= \frac{17}{5} \\& = \bold{ 3\frac{2}{5} } \\ \\ \small{ \blue{ \mathfrak{semoga \: membantu \: :) }}} \end{aligned}[/tex]
