Question

Find P such that 35:p :: 25:7

Answer 1

Answer:

The value of p will be$9.8$.

Step-by-step explanation:

Given: $35:p :: 25:7$

We have to find the value of p.

• As we know that a proportion is an equation in which two ratios are set equal to each other.
• The formula for proportion is:
• Product of extremes = The product of means
• For example,

       $a:b::c:d\\=>a\times d=b\times c$

We are solving in the following way:  

We have,

$35:p :: 25:7$

By the formula for proportion:

$=>35\times7=p\times 25\\=>245=25p\\\\=>p=\frac{245}{25} \\\\=>p=\frac{49}{5} \\\\=>p=9.8$
