Question

find value of p fast​

Answer 1

Answer:

Ans: 2.1

Step-by-step explanation:

2/3P . 5/2=7/2

or,2/3P=7/2×2/5

or,2/3P=7/5

or,P=7×3/5×2

or,P=21/10

or,P=2.1

Answer 2

Question:-

Find the value of p

$\frac{2}{3} p \times 2\frac{1}{2} = 3 \frac{1}{2}$

Solution:-

$→ \: \frac{2}{3} p \times \frac{5}{2} = \frac{7}{2} \\ \\ (here \:2 \: gets \: cancel) \\ therefore \: the \: fraction \: becomes\\ \\ →\: \frac{5}{3} p = \frac{7}{2} \\ \\ →\: p = \frac{7}{2} \times \frac{3}{5} \\ \\ →\: p = \frac{7}{2} \div \frac{5}{3} \\ \\ →\: p = \frac{7}{2} \times \frac{3}{5} \\ \\→\: p = \frac{21}{10}$

Verifying it:-

$L.H.S \: = \frac{2}{3} p \times \frac{5}{2} \\ \\ putting \: the \: value \: of \: p \: \\ = \frac{2}{3} \times \frac{21}{10} \times \frac{5}{2}\\ \\ = \frac{7}{2} \: = \: R.H.S.$

Answer:-

Therefore,

The value of p is 21/10.
