Question

Please help multiply this

Answer 1

1st Answer ⬇️

$1) \: 2 \frac{1}{5} + 1 \frac{1}{4} - \frac{1}{2} \\ \\ \\ \implies \: \frac{11}{5} + \frac{5}{4} - \frac{1}{2} \\ \\ \\ \implies \: \frac{11}{5} + \frac{5 - 2}{4} \\ \\ \implies \: \frac{11}{5} + \frac{3}{4} \\ \\ \\ \implies \: \frac{44 + 15}{20} \\ \\ \\ \implies \: \frac{59}{20}$

2nd Answer⬇️

$2) \: \frac{2}{7} \times \frac{7}{9} \times \frac{9}{14} \times 6 \frac{1}{3} \\ \\ \implies \: \frac{2 \times 7}{7 \times 9} \times \frac{9}{14} \times \frac{19}{3} \\ \\ \implies \: \frac{ \cancel{14} \small2}{ \cancel{63} \small9} \times \frac{9 \times 19}{ 14\times 3} \\ \\ \implies \: \frac{2}{9} \times \frac{171}{42} \\ \\ \implies \: \frac{342}{378}$

3rd Answer⬇️

• As we know Area of rectangal = l×b
• Length = 5 ¼ = 21/4
• Breadth = 1 1/7 = 8/7
• $\sf \: area = \dfrac{21}{4} \times \dfrac{8}{7} \\ \\ \mathcal{ \implies \: 6 {m}^{2}}$

4th Answer⬇️

• Each student consumed Milk
• $= 1 \frac{5}{6} \\ = \frac{11}{6}$
• Total Milk Consumed Per Day= 308 litres
• Number Of Students,
• = Each Student Consumed/Total Consumed
• = 308÷11/6
• = 308 × 6/11
• = 168

Hence The Number of students in Hostel are 168 students.
