Question

In a school, there are a total of 6300 classrooms. The ratio of the number of laro
classrooms to small classrooms is 1 : 5. Find the number of large classrooms ar
small classrooms in the school.​

Answer 1

Given:

• Total = 6300 students
• Large classrooms = 1x = x
• Small classrooms = 5x

To find:

Number of large classrooms and small classrooms = ?

Solution:

Since there are 6300 students totally,

the sum of ratios would be 6300

➥ x + 5x = 6300

➝ 6x = 6300

➝ x = 6300 ÷ 6

➝ x = 1050

So,

• Number of students in large classrooms = x = 1050 students
• Number of students in small classrooms = 5x = 5250 students.

Verification:

The sum of 2 ratios should be equal to 3600.

1050 + 5250 = 6300

→ 6300 = 6300

• ☯ In a school, there are a total of 6300 classrooms. The ratio of the number of large classrooms to small classrooms is 1 : 5. Find the number of large classrooms and small classrooms in the school.

❃ Gɪᴠᴇɴ Iɴғᴏ ☟

☯ No. of classrooms in the school ➠ 6300 classrooms.

☯ The ratio of the number of large classrooms to small classrooms ➠ 1 : 5.

❃ Tᴏ Fɪɴᴅ ☟

☯ The number of large classrooms and small classrooms in the school.

✯ Cᴏʀʀᴇᴄᴛ Aɴsᴡᴇʀ ☟

❖ Firstly, finding number of large classroom,

✠ As we know that ☟

• ☯ Total no. of classrooms × First no. of the ratio / Sum of the ratio .

❀ Total no. of classrooms ➯ 6300

❀ First no. of the ratio ➯ 1

❀ Sum of the ratio ➯ 5 + 1 ➣ 6

✡ Then,

➯ 6300 × 1 / 6

➠ 1050

∴ Hence, the number of large classroom is 1050.

❖ Secondly, finding number of small classroom,

✠ As we know that ☟

• ☯ Total no. of classrooms × Second no. of the ratio / Sum of the ratio

❀ Total no. of classrooms ➯ 6300

❀ First no. of the ratio ➯ 5

❀ Sum of the ratio ➯ 5 + 1 ➣ 6

✡ Then,

➯ 6300 × 5 / 6

➠ 5250

∴ Hence, the number of small classroom is 5250.
