Answer 1

Respuesta:

a. 6/3-4/6-1/3 = 1

b. 7/6-(-2/5)-3/4 = 49/ 60   (Decimal: 0.816667)

c. (-2/3)-(-7/6) = 1 /2   (Decimal: 0.5)

d. (-13/5)-(-72/5)=  59 /5 (Decimal: 11.8)

e. (-21/34)-(-17/9)=  389 /306   (Decimal: 1.271242)

Explicación paso a paso:

a. 6/3-4/6-1/3 =

=2− 4 /6 − 1/3

=2− 2 /3 − 1/ 3

= 4/ 3 − 1 /3

=1

b. 7/6-(-2/5)-3/4 =

= 47 /30 − 3 /4

= 49 /60

c. (-2/3)-(-7/6) =

= −2/ 3 −  −7 /6

= −2/ 3 + 7 /6

= −4 /6 + 7/ 6

= −4+7 /6

= 3/ 6

simplificado =1 /2

d. (-13/5)-(-72/5) =

= −13 /5 − −72 /5

= −13 /5 + 72/ 5

= −13+72 /5

= 59 /5

e. (-21/34)-(-17/9)=

= −21 /34 − −17 /9

= −21 /34 + 17 /9

= −189 /306 + 578/3 06

= −189+578 /306

= 389 /306
