romanna [79]

Answer:

Multiples of 60

Step-by-step explanation:

If a a number finished with a 0, (unless it is 0) than it is divisible by 2 and 5.

If a number is divisible by 20 then it is divisible by 4. Finally if its divisible by 6 then it is by 3 too.

60 is the first number that satisfies all of the constraints and so does any of its multiples (up to 180 in this case)

Which fraction is greater? how do you know? a) 2/3 , 2/5​
rusak2 [61]

Answer:

2/3 is greater

Step-by-step explanation:

Two fractions can only be compared if their denominators are equal. In the given problem they are different, so first we make them equal.

\frac{2}{3}  =  \frac{2 \times 5}{3 \times 5}  =  \frac{10}{15}  \\  \\  \frac{2}{5}  =  \frac{2 \times 3}{5 \times 3}  =  \frac{6}{15} \\  \\   \because \: \frac{10}{15} > \frac{6}{15} \\  \\  \purple{ \boxed{ \bold{ \therefore \: \frac{2}{3}   > \frac{2}{5}  }}}
