[tex] \frac{1}{2} - \frac{7}{ \frac{1}{3} + \frac{3}{5} } [/tex]
TERIMA KASIH YANG BANTU.

Jawab:

Penjelasan dengan langkah-langkah:

(1/3) + (3/5) = (1 × 5)/(3 × 5) + (3 × 3)/(3 × 5)

= (5/15) + (9/15)

= (5 + 9)/15

= 14/15

7/((1/3) + (3/5)) = 7/(14/15)

= 7 × (15/14)

= 15/2

= 7½

½ - 7½ = -7

½ - (7/((1/3) + (3/5))) = -7

$\displaystyle\rm~\frac{1}{2} - \frac{7}{ \frac{1}{3} + \frac{3}{5} } = -7$

Penjelasan dengan langkah-langkah:

$\displaystyle\rm~\frac{1}{2} - \frac{7}{ \frac{1}{3} + \frac{3}{5} } = \frac{1}{2} - \frac{7}{ \frac{5}{15} + \frac{9}{15} } \\ \\ \displaystyle\rm~ = \frac{1}{2} - \frac{7}{ \frac{5 + 9}{15} } \\ \\ \displaystyle\rm~ = \frac{1}{2} - \frac{7}{ \frac{14}{15} } \\ \\ \displaystyle\rm~ = \frac{1}{2} - \frac{105}{14} \\ \\ \displaystyle\rm~ = \frac{7}{14} - \frac{105}{14} \\ \\ \displaystyle\rm~ = \frac{7 - 105}{14} \\ \\ \displaystyle\rm~ = -\frac{98}{14} \\ \\ \displaystyle\rm~ = -7$
