Question

Add or Subtract.
Write each answer in its simplest form​

Answer 1

Step-by-step explanation:

3(1/8)+1(5/6)

=[(3*8+1)/8] +[(1*6+5)/6]

=(25/8)+(11/6)

=(1/2) [(25/4)+(11/3)]

=(1/2) [(75+44)/12]

=(1/2) (119/12)

=119/24

16(5/7)-8(2/5)

=[(16*7+5)/7] -[(8*5+2)/5]

=(117/7)-(42/5)

=(585-294)/35

=291/35

Answer 2

Answer

$\large\star\mathfrak\pink{Given}\star$

$1)\longrightarrow$ $3 \dfrac{1}{8} + 1\dfrac{5}{6}$

$\large\star\mathfrak\green{Solution}\star$

$\longrightarrow$ $3 \dfrac{1}{8} + 1\dfrac{5}{6}$

$\rightarrow$ $\dfrac{25}{8} + \dfrac{11}{6}$

$\rightarrow$ $\dfrac{75 + 44}{24}$

$\rightarrow$ $\dfrac{119}{24}$

$\rightarrow$ $4.958$

$\therefore$ $The \: answe\: of \: this \: question \: is \: 4.958$

$\large\mathfrak\purple{Given :-}$

$2)\Longrightarrow$ $16\dfrac{5}{7} - 8\dfrac{2}{5}$

$\large\mathfrak\orange{Solution :-}$

$\Longrightarrow$ $16\dfrac{5}{7} - 8\dfrac{2}{5}$

$\Rightarrow$ $\dfrac{117}{7} - \dfrac{42}{5}$

$\Rightarrow$ $\dfrac{585 - 294}{35}$

$\Rightarrow$ $\dfrac{291}{35}$

$\Rightarrow$ $8.314$

$\therefore$ $The \: answer \: of \: this \: question \: is \: 8.314$
