Answer 1

Answer:

Step-by-step explanation:

Total money spen by him is

11/2+21/4

LCM OF 2 AND 4 IS 4 SO

(22+21)/4

43/4=RS.10.75

Answer 2

1 pencil cost=$1\frac{1}{2}$

When we change mixed Fraction in Fraction.

2×1+1=3/2

1 pencil Cost=₹$\frac{3}{2}$

1 Sharpener Cost=$2\frac{1}{4}$

In Fraction

4×2+1=9/4

1 Sharpener Cost=₹$\frac{9}{4}$

Total Cost

$\frac{3}{2} + \frac{9}{4} \\ \\ lcm = 4 \\ \\ \frac{3 \times 2 + 9}{4} \\ \\ \frac{15}{4}$

15/4 in mixed Fraction=3 3/4

Total Cost=

₹$3\frac{3}{4}$
