Question

Select all of the number sentences that are true. 8 4 2 1 10 11 35 D. 11 J : 84 - 1 2등 3 1 = 3 o D. 123 : 64 = 2 19

Answer 1

options B and D

Step-by-step explanation:

we check the options and simplify:

`\begin{gathered} 8(2)/(3)\colon\text{ 4}(1)/(8) \\ (26)/(3)\colon(33)/(8) \\ \colon\text{ means division} \\ (26)/(3)*(8)/(33)\text{ =}(208)/(99) \\ (208)/(99)\text{ is not equal to }2(1)/(10) \end{gathered}`
`\begin{gathered} 11(1)/(2)\colon\text{ 8}(3)/(4) \\ (23)/(2)\colon(35)/(4)\text{ =}(23)/(2)*(4)/(35)\text{ = 46/35} \\ =\text{ 1}\frac{11}{35\text{ }}\text{ } \\ \text{this is correct} \end{gathered}`
`\begin{gathered} 2(5)/(6)\colon3(1)/(4)\text{ = }(17)/(6)\colon(13)/(4)\text{ = }(17)/(6)*(4)/(13)=\text{ }(34)/(39) \\ \\ =\text{ }(34)/(39)\text{ is not equal to }3(1)/(9) \end{gathered}`
`\begin{gathered} 12(2)/(3)\colon\text{ 6}(1)/(4)\text{ = }(38)/(3)\colon\text{ }(25)/(4)\text{ = }(38)/(3)*\text{ }(4)/(25)\text{ = }(152)/(75) \\ =\text{ 2}(2)/(75)\text{ correct} \\ \end{gathered}`
