Answer 1

Respuesta:

* 1/5 ÷ ( 1/3 ÷ 5/3 ) = 1

* ( 3/7 x 1/4 ) ÷ 1/7 = 3/4

* 3¹/₇ + ( 10¹/₂ ÷ 1¹/₃ ) = 11¹/₅₆

* ( 1/2 + 3/5 ) ÷ ( 1/7 + 3/7 ) = 1³⁷/₄₀

Explicación paso a paso:

* 1/5 ÷ ( 1/3 ÷ 5/3 ) = 1/5 ÷ ( 1 x 3 / 3 x 5 )

= 1/5 ÷ 3/15 = 1 x 15 / 5 x 3 =15/15 = 1

* ( 3/7 x 1/4 ) ÷ 1/7 = ( 3 x 1 / 7 x 4 ) ÷ 1/7

= 3/28 ÷ 1/7 = 3 x 7 / 28 x 1 = 21/28 = 3/4

* 3¹/₇ + ( 10¹/₂ ÷ 1¹/₃ ) = 22/7 + ( 21/2 ÷ 4/3 )

= 22/7 + ( 21 x 3 / 2 x 4 )  = 22/7 + 63/8

= 22 x 8 / 7 x 8 + 63 x 7 / 8 x 7 = 176/56 + 441/56

= 617/56 = 11¹/₅₆

*  ( 1/2 + 3/5 ) ÷ ( 1/7 + 3/7 ) = ( 1 x 5 / 2 x 5 + 3 x 2 / 5 x 2 ) ÷ ( 4/7 )

= ( 5/10 + 6/10 ) ÷ 4/7 = 11/10 ÷ 4/7

= 11 x 7 / 10 x 4 = 77/40 = 1³⁷/₄₀
