Answer 1

AnswEr:

$\sf{Given} \begin{cases}\sf{Total\; Number\:of\: Students\: is\: 95}\\ \sf{Number\:of \:Girls\:is \: 45}\end{cases}$

To Find :

Ratio Number of boys to total number of Girls

Explanation:

Let us Consider that Number of boys in class be x.

$\bold{\underline{\sf{According\:to\: Questions\:Now,}}}$

$\longrightarrow\sf\: x + 45 = 95$

$\longrightarrow\sf\: x = 95 - 45$

$\longrightarrow\small{\underline{\boxed{\sf{\red{x\:=\:50}}}}}$

Number of Boys = 50 & Number of Girls = 45

So , Ratio is 50 : 45

$\longrightarrow\sf\: 10: 9$

$\bold{\underline{\sf{Hence,\: Required\: Ratio\: is \:10:9.}}}$

Answer 2

Answer:

$\boxed{\red{\bf Ratio = 10 : 9}}$

Step-by-step explanation:

Given that :

• Total number of students in the class is 95.
• Total number of boys in the class is 45.

To find :

• The ratio of total number of boys to the total number of girls.

Solution:

Let the number of boys in the class be x.

According to the question,

Total number of students = 95

$\sf \implies x + 45 = 95\\\\\implies \sf x = 95 - 45 \\\\\implies \sf \boxed{\bf \therefore x = 50}$

Now,

We need to find the ratio of total number of boys to the total number of girls,

$\sf \longrightarrow Ratio = 50 : 45 \\\\\sf \longrightarrow Ratio = 10 : 9$

Hence, the required ratio is 10 : 9.
