Question

A glass is 1/2 full. Then 65cm^3 of orange juice is poured in. The glass is now 6/7 full. What is the total volume of the glass? = ....... cm ^3

Answer 1

Answer:

Volume: 1/2V + 65 = 6/7V

(Half glass added by Orange juice is equal to 6/7 of thr glass being full)

Multiply by 14 (To cancel the denominators. 7 can't cancel with 2 so take 14)

7V + 910 = 12V

5V= 910

V= 182

Thus, Volume of glass is 182 cm³

Answer 2

ANSWER...

A glass is 1/2 means = 3.5 / 7

if 65cm^3 is poured means = 6 /7

then 65cm^3 = 2.5/7

volume be x

therefore

(2.5 × X ) / 7 = 65

X =( 65×7) / 2.5

X = 455 / 2.5

total volume of glass = 182 cm^3
