Question

n estou conseguindo alguem pode me ajudar?

Answer 1

Resposta:

a) 1/2

b) 1/12

c) 1/5

d) 5/16

e) 1/6

f) 11/20

g) 1/6

h) 0

Explicação passo-a-passo:

a) A = 5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2

b) B = 7/12 - 1/2 = 7/12 - 6/12 = 1/12

c) C = 3/10 - 1/10 = 2/10 = 1/5

d) D = 15/16 - 5/8 = 15/16 - 10/16 = 5/16

e) E = 5/12 - 1/4 = 5/12 - 3/12 = 2/12 = 1/6

f) F = 17/20 - 3/10 = 17/20 - 6/20 = 11/20

g) G = 1/2 - 1/3 = 3/6 - 2/6 = 1/6

h) H = 2/6 - 1/3 = 2/6 - 2/6 = 0

Answer 2

Explicação passo-a-passo:

.

$\dfrac{1}{3} + a = \dfrac{5}{6}$

$a = \dfrac{5}{6} - \dfrac{1}{3}$

$a = \dfrac{5 - 2}{6}$

$a = \dfrac{3}{6}$

$a = \dfrac{3÷3 }{6 \div 3}$

$a = \dfrac{1}{2}$

.

$\dfrac{1}{2} + b = \dfrac{7}{12}$

$b = \dfrac{7}{12} - \dfrac{1}{2}$

$b = \dfrac{7 - 6}{12}$

$b = \dfrac{1}{12}$

.

$c + \dfrac{1}{10} = \dfrac{3}{10}$

$c = \dfrac{3}{10} - \dfrac{1}{10}$

$c = \dfrac{2÷2}{10\div2}$

$c = \dfrac{1}{5}$

.

$d + \dfrac{5}{8} = \dfrac{15}{16}$

$d = \dfrac{15}{16} - \dfrac{5}{8}$

$d = \dfrac{15 - 10}{16}$

$d = \dfrac{5}{16}$

.

$e + \dfrac{1}{4} = \dfrac{5}{12}$

$e = \dfrac{5}{12} - \dfrac{1}{4}$

$e = \dfrac{5 - 3}{12}$

$e = \dfrac{2÷2}{12\div2}$

$e = \dfrac{1}{6}$

.

$\dfrac{3}{10} + f = \dfrac{17}{20}$

$f = \dfrac{17}{20} - \dfrac{3}{10}$

$f = \dfrac{17 - 6}{20}$

$f = \dfrac{11}{20}$

.

$\dfrac{1}{3} + g = \dfrac{1}{2}$

$g = \dfrac{1}{2} - \dfrac{1}{3}$

$g = \dfrac{3 - 2}{6}$

$g = \dfrac{1}{6}$

.

$h + \dfrac{1}{3} = \dfrac{2}{6}$

$h = \dfrac{2}{6} - \dfrac{1}{3}$

$h = \dfrac{2 ÷ 2}{6 \div 2} - \dfrac{1}{3}$

$h = \dfrac{1}{3} - \dfrac{1}{3}$

$h = 0$
