Question

1. in a proportion, the second, 3rd and 4th terms are 7,35 and 49 respectively. find the first term.​

Answer 1

Answer:

5

Step-by-step explanation:

Let first term be "x"

Since they are in proportion, so,

x:7:35:49

PRODUCT OF EXTREMES = 49 × x

PRODUCT OF MEANS = 35×7

Product of Extremes = Product of means

= x = (35×7)/49

cancel 7 with 49, then finally cancel 35 with 7 since (49/7=7)

X = 5 ( Answer )

I HOPE IT IS CLEAR TO YOU.
