Answer 1

Answer:

18 computer are needed for 30 students

Answer 2

Answer:

$\rm \: {\green {Number \: of \: computers \: needed \: for \: 30 \: students \: Is \: 18}}$

Step-by-step explanation:

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \rm{ \purple{GiveN}}}}}}}$

• In a computer lab in the school there a 6 computers for every 10 students.

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \rm{ \purple{To\: Find}}}}}}}$

• How many computers will be needed for 30 students.

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \rm{ { \star}{ \purple{Solution} { \star}}}}}}}}$

• 6 computers for 10 students

• So, how many computers for one student.

• Let x computers be needed for 1 student.

• 6 $\longmapsto$ 10

• x$\longmapsto$ 1

• Now do cross multiplication

• $\rm 10x = 6$

• $\rm \frac{6}{10} = x$

• $\bf x = \frac{6}{10}$

• So, 1 student will need $\frac{6}{10}$computer

• Our question is to find the number of computers for 30 students

• Now, answer is easy, we got the number of computers for 1 student.. Now, simply multiply The number of computers for 1 student × 30

• So, $\rm \frac{6}{10} \times 30$

• $\rm \frac{6}{1\cancel0} \times 3 \cancel0$

• $\rm 6 \times 3$

• $\rm 18$

So, $\therefore$ Number of computers needed for 30 students Is 18
