Question

(1) (-5) × 12
(2) 98 ÷ (-7)

find the HCF of 10 ,15 and 12

Add 1 2/3 + 2 4/5

​

Answer 1

$\huge{ \color{aqua}{ \underbrace{ \underline{ \color{lime}{ \mathbb{࿐SoLuTiOn࿐}}}}}}$

$1 .\: = ( - 5) \times 12 \\ = - 60$

$2. \ = : 98 \div ( - 7) \\ = - 14$

$3. \: = 1 \frac{2}{3} + 2 \frac{4}{5} \\ = \frac{5}{3} + \frac{14}{5} \\ = \frac{25 + 42}{15} \\ = \frac{67}{15}$

Answer 2

Answer:

\huge{ \color{aqua}{ \underbrace{ \underline{ \color{lime}{ \mathbb{࿐SoLuTiOn࿐}}}}}}

࿐SoLuTiOn࿐

\begin{lgathered}1 .\: = ( - 5) \times 12 \\ = - 60\end{lgathered}

1.=(−5)×12

=−60

\begin{lgathered}2. \ = : 98 \div ( - 7) \\ = - 14\end{lgathered}

2. =:98÷(−7)

=−14

\begin{lgathered}3. \: = 1 \frac{2}{3} + 2 \frac{4}{5} \\ = \frac{5}{3} + \frac{14}{5} \\ = \frac{25 + 42}{15} \\ = \frac{67}{15}\end{lgathered}
