Fill in the blanks<br>864+2006=--------+864<br><br>5351 +(574+799)= 574+(5351+_____)

Mama L [17]

Answer:

2006

799

Step-by-step explanation:

Given the expression:

The right hand side of the sun must be equal to the left hand side ;

Therefore ;

864+2006=--------+864

The sum of 864 and 2006 must be equal to the right hand side sum ; hence

864+2006= 2006 +864

Similarly, the left hand side and right havd side must also be equal here ;

5351 + 574 + 799 = 574 + 5351 + 799

Hence, the missing value is 799

SOMEONE PLEASE HELP!! I've tried this question twice and I just can't seem to get it

$\underline{\underline{\large\bf{Given:-}}}$

$\red{\leadsto}\:$ $\textsf{Total Number of fish }$ $\sf = 30$

$\red{\leadsto}\:$ $\textsf{ Number of carp fish }$ $\sf = 9$

$\underline{\underline{\large\bf{To Find:-}}}$

$\orange{\leadsto}\:$ $\textsf{ Ratio of carp to sticklebacks to tench }$ $\sf in \:the \:pond$

$\\$

$\underline{\underline{\large\bf{Solution:-}}}\\$

$\longrightarrow$ Number of fish that are not carp = Total fish - number of carp fish

$\begin{gathered}\implies\quad \sf 30-9 \\\end{gathered}$

$\begin{gathered}\implies\quad \sf 21 \\\end{gathered}$

$\longrightarrow$ Since 1/3 of remaining fish which are not carp are sticklebacks , Number of sticklebacks =

$\begin{gathered}\implies\quad \sf \frac{1}{3} \times number \:of \:remaining \: fish\\\end{gathered}$

$\begin{gathered}\implies\quad \sf \frac{1}{3}\times 21 \\\end{gathered}$

$\begin{gathered}\implies\quad \sf 7 \\\end{gathered}$

<u>Now</u> ,

$\longrightarrow$ Number of tench = Total number of fish - (Number of carp + Number of sticklebacks)

$\begin{gathered}\implies\quad \sf 30-(9+7) \\\end{gathered}$

$\begin{gathered}\implies\quad \sf 30-16\\\end{gathered}$

$\begin{gathered}\implies\quad \sf 14\\\end{gathered}$

$\therefore$ Ratio of carp to sticklebacks to tench in the pond =

$\begin{gathered}\quad\quad \boxed{\sf {9: 7:14}} \\\end{gathered}$
