A pet store sells a fish bowl that holds 6/8 gallon of water. It also sells a smaller fish bowl. Which amount of water is less than 6/8 gallon?
A. 3/4gal
B. 4/5gal
C. 7/9gal
D. 6/10gal
I think its D but I'm not sure cause I don't get how to find which one is smaller than 6/8
Convert them to fractions with a common denominator.
135/180, 144/180, 140/180, 108/180
6/8 = 3/4 = 135/180
You're right. D. is the answer.

We could also change these fractions to decimals.
How do you make a fraction sign? Is it /
Yes.
/ means a fraction and division.
To determine which amount of water is less than 6/8 gallon, we need to compare each option to 6/8 gallon.
To compare fractions, we can convert them to a common denominator. In this case, we can use 8 as the common denominator since it is already the denominator for 6/8 gallon.
Option A: 3/4 gallon. To convert this fraction to have a denominator of 8, we multiply the numerator and denominator by 2. So, 3/4 gallon is equal to (3*2)/(4*2) = 6/8 gallon.
Option B: 4/5 gallon. To convert this fraction to have a denominator of 8, we multiply the numerator and denominator by 8/5. So, 4/5 gallon is equal to (4*8)/(5*8) = 32/40 gallon. Since 32/40 is greater than 6/8, Option B is not less than 6/8 gallon.
Option C: 7/9 gallon. To convert this fraction to have a denominator of 8, we multiply the numerator and denominator by 8/9. So, 7/9 gallon is equal to (7*8)/(9*8) = 56/72 gallon. Since 56/72 is greater than 6/8, Option C is not less than 6/8 gallon.
Option D: 6/10 gallon. To convert this fraction to have a denominator of 8, we multiply the numerator and denominator by 8/10. So, 6/10 gallon is equal to (6*8)/(10*8) = 48/80 gallon. Since 48/80 is greater than 6/8, Option D is not less than 6/8 gallon.
Based on the comparisons, the amount of water that is less than 6/8 gallon is Option A: 3/4 gallon.
