Answer 1

Resposta:

Olá bom dia!

21/4 ÷ 7/3 - 14/3 + 16/3 * 7/2

= 21/4 * 3/7 - 14/3 + 112/6

= 63/28 - 14/3 + 112/6

= [ (63*3 - 14*28)/ 84 ] + 112/6

= (189 - 392)/84] +112/6

= -203/84 + 112/6

= (-203*6 + 112*84) / 504

= (-1218+ 9408) /504

= 8190/504 (:2)

= 4095 / 252 (:3)

= 1365 / 84 (:3)

= 455 / 28 (:7)

= 65/4
