Question

Find the third proportional to 5.25, 7 please give me my answer

Answer 1

Let x be the third proportional
A/b=b/c
525/700=7/x
Product of extreme =525*x=525x
Product of mean=700*7=4900
Product of extreme=product of mean
525x=4900
X=4900/525
X=9.33
I hope my answer is correct

Answer 2

Answer:

hey mate........here is your answer

Step-by-step explanation:

let third proportion be x

so,

5.25 : 7 = 7 : x

so,

product of extremes = product of means

REMEMBER

AS WE REMOVE A DECIMAL POINT WE ADD A ZERO IN THE OPPOSITE NUMBER

SO, 5.25/7 = 525/700

now ,

product of extremes = 525x

product of means = 700 × 7 = 4900

then we will find the value of x

so,

x = 4900/525

answer = 9.33
