Answer 1

Explicação passo a passo:

4/3+6/5×5/4+/4÷3/8​

6/5 * 5/4 = ( 6 * 5 )/ ( 5 * 4 ) = 30/20 corta zero = 3/2 >>>>>

reescreevendo

( 4/3 + 3/2)/ ( 4 : 3/8 )

4/1 : 3/8 = 4/1 * 8/3 = ( 4 * 8 )/ ( 1* 3 ) = 32/3 >>>>>

reescrevendo

( 4/3 + 3/2 )/ 32/3

4/3 + 3/2 =

mmc 3 e 2 = 6

divide pelos denominadores e multiplica pelos numeradores

4/3 + 3/2 = ( 8 + 9)/6 = 17/6 >>>>> numerador

17/6 : 32/3 17/6 * 3/32 = ( 17 * 3 )/ ( 6 * 32 ) = 51/192 >>>>por 3 = 17/64 >>>>>resposta
