Question

12.8 x 3/4 I don’t know it

Answer 1

48/5 or 9 3/5

12.8/1 x 3/4 = 38.4/4

Or multiply 12.8/1 by 10 ==> 128/10

128/10 x 3/4 = 384/40

Hope this helps!

Answer 2

Your question :

• 
  `\sf{12.8 \: * \: (3)/(4) }`

Aim :

• We have to multiply them.

Solution :

`: \: \implies \: \sf{12.8 \: * \: (3)/(4) } \\ \\ : \: \implies \: \sf{ (128)/(10) \: * \: (3)/(4) } \\ \\ : \: \implies \: \sf{ (384)/(10 * 4) } \\ \\ : \: \implies \: \sf{ (384)/(40) } \\ \\ : \: \implies \: \sf{ \cancel(384)/(40) } \\ \\ : \: \implies \: \sf{ (192)/(20) } \\ \\ : \: \implies \: \sf{ \cancel(192)/(20) } \\ \\ : \: \implies \: \sf{ (96)/(10) } \\ \\ : \: \implies \: \red{\bf{9.6}}`
