Is 8/15 less than 2/5

8/15 is greater than 2/5

Step-by-step explanation:

Get a common denominator of 15

8/15   compared to 2/5*3/3

8/15  compared to 6/15

8/15 is greater than 2/5

No

Step-by-step explanation: Notice that the fractions that we're comparing in this problem have different denominators. When fractions have different denominators, they're called unlike fractions.

To compare unlike fractions, we must first get a common denominator.

The common denominator of 15 and 5 will be the

least common multiple of 15 and 5 or 15.

Notice that 8/15 already has a 15 in the

denominators so it stays the same.

To get a 15 in the denominator of 2/5, we multiply the numerator and the denominator by 3 which gives us 6/15.

Notice that we now have like fractions, 8/15 and 6/15, since both fractions have a 15 in the denominator.

To compare like fractions, we simply look at the numerators.

Here, since 8 is greater than 6, 8/15 is greater than 6/15.

This means that 8/15 is greater than 2/5.

So no, 8/15 is not less than 2/5.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
