numbers:-13 1/3and1 1/8​

Answer 1

Step-by-step explanation:

Communtative Property of multiplication-

$\color{black}\boxed{\colorbox{saffron}{a×b=b×a}}$

ㅤ

Proving-

$13\frac{1}{3} \times 1\frac{1}{8} = 1 \frac{1}{8} \times 13 \frac{1}{3} \\ \\ = \frac{40}{3} \times \frac{9}{8} = \frac{9}{8} \times \frac{40}{3} \\ \\ = 5 \times 3 = 3 \times 5 \\ \\ = 15 = 15$

Hence proved.

Answer obtained respectively.

Answer 2

Answer:

formula for comulative frequency

$\huge \bold{ \boxed{a \times b = b \times a}}$

$\bold{ \underline{prof - }}$

$l.h.s \\ 13\frac{1}{3} \times 1 \frac{1}{8} \\ \longrightarrow \: \frac{40}{3} \times \frac{9}{8} \\ \longrightarrow \: 5 \times 3 = 15 \\ \\ r.h.s \\ 1\frac{1}{8} \times 13 \frac{1}{3} \\ \longrightarrow \: \frac{9}{8} \times \frac{40}{3} \\ \longrightarrow \: 3 \times 5 = 15 \\ \\ hence \: both \: l.h.s = r.h.s \\ \\ \bold{ \underline{ \underline{hence \: profed \: respectively}}}$
