Question

Please help me with the 3rd question

Answer 1

Answer:

the answer is x = 104

Step-by-step explanation:

from the chapter ratio and proportion :

the product of extremes = the product of mean

so you multiply

1.3 × 8.8 = x × 1.1

now take 1.1 to the other side which makes it

(1.3 × 8.8) / 1.1 = x

now multiply the left hand side by 10 to make things easier

(13 × 88) / 11 = x

cross multiply :

13 × 8 = x

104. = x

therefore the value of x is 104.

hope it helps......

Answer 2

Answer :

• The question is from the ratio and proportion.

= 1.3 : 1.1 :: x : 8.8

= $\dfrac{1.3}{1.1}$ = $\dfrac{x}{8.8}$

= 1.1x = 8.8 × 1.3

= 1.1x = 11.44

= x = $\dfrac{11.44}{1.1}$

= x = 10.4

The value of x is 10.4 respectively !
